Ratatan weapon crafting is the central progression loop behind every late-stage build, and Version 1.0 changed the math by adding a fourth limit break stage that lifted the ceiling from 90 to 100. This ratatan weapon crafting walkthrough breaks down where to farm upgrade materials, how each limit break tier works, and the order in which to push a Mythic weapon from level 1 all the way to the new cap. If you have been stockpiling Decorune shards or wondering which Episode 3 drops actually matter, the next sections will save you dozens of runs.
Ratatan Weapon Crafting Basics and Material Tiers
Every weapon in Ratatan runs through the same crafting pipeline: earn it, level it, and then limit break it when the soft cap stops accepting XP. Materials gate the entire curve, and they are split into rarity tiers that line up with Episode unlocks. New players burn through Common Scrap and Iron Sand without thinking, but the moment a weapon hits its first wall, the conversation shifts to Decorune, Mythic Cores, and the rarer limit break catalysts.
The Crafting Material Hierarchy
Ratatan sorts every consumable into four practical tiers, and the Version 1.0 update added a fifth tier tied directly to the new limit break stage. Knowing which tier you actually need prevents the most common mistake: spending Mythic-level materials on a Common weapon.
| Material Tier | Primary Use | Common Source | Rarity |
|---|---|---|---|
| Common Scrap | Level 1–40 upgrades | Stage drops, mob kills | Common |
| Iron Sand | Level 40–70 upgrades | Mid-bosses, chest rooms | Uncommon |
| Decorune | Level 70–90 upgrades | Episode 2 onward, Mythic drops | Rare |
| Mythic Core | Mythic weapon XP filler | Episode 3 reward pools, boss chests | Epic |
| Refined Decorune | 4th limit break catalyst | Version 1.0 boss drops, Episode 3+ | Legendary |
The hierarchy matters because the Upgrade Material Set on Steam bundles the four lowest tiers, but it cannot substitute for Refined Decorune, which only entered the drop pool with the 1.0 patch. According to the official store description, the bundle shortens the early climb rather than replacing endgame farming, so treat it as a starter pack instead of a long-term solution.
Where Each Material Actually Drops
The drop table is surprisingly narrow once you filter out the noise. Common Scrap falls off every trash mob, and Iron Sand is concentrated in the chest rooms that appear every third stage. Decorune is the first material that demands attention: it shows up in Episode 2 reward pools, on mid-boss kills, and in any chest that glows gold rather than silver.
| Source | Materials You'll See | Best Stage Range |
|---|---|---|
| Trash mobs | Common Scrap | All episodes |
| Silver chests | Iron Sand, Common Scrap | Stage 1–6 |
| Gold chests | Decorune, Iron Sand | Stage 4+ |
| Mid-bosses | Decorune, Mythic Core shards | Episode 2+ |
| Stage bosses | Mythic Core, Refined Decorune (1.0+) | Episode 3+ |
Community testing suggests gold chest density peaks in Episode 2, which is why most players target that episode for the first Decorune stockpile. If you want a deeper look at how Episode 2 and Episode 3 unlocks feed the crafting loop, the ratatan difficulty guide explains the oath level and welcome mode settings that speed up those runs.
Ratatan Weapon Upgrades: Leveling From 1 to 90
Before any limit break enters the picture, every weapon has to climb the base level curve. The base cap of 90 is the longest grind in Ratatan, and the upgrade costs scale aggressively past level 50. Players who skip the early levels on a new Mythic often regret it later, because every limit break resets the cap but not the underlying XP cost curve relative to the new ceiling.
Upgrade Cost Curve by Weapon Rarity
Upgrade costs are not flat across rarities. A Rare weapon at level 50 costs roughly a third of what a Mythic weapon costs at the same level, but the Mythic pays that price back with higher stat multipliers. The table below captures the broad brackets reported by players; exact values drift slightly with patches, so treat the numbers as planning anchors rather than exact math.
| Weapon Rarity | Avg. Materials to Reach Lv. 40 | Avg. Materials to Reach Lv. 70 | Avg. Materials to Reach Lv. 90 |
|---|---|---|---|
| Common | 120 Common Scrap | 380 Common Scrap | Not recommended |
| Rare | 80 Common + 40 Iron | 200 Iron Sand | 400 Iron Sand + 80 Decorune |
| Epic | 60 Common + 60 Iron | 220 Iron + 40 Decorune | 380 Decorune + 60 Mythic Core |
| Mythic | 40 Common + 80 Iron | 180 Iron + 80 Decorune | 320 Decorune + 120 Mythic Core |
The pattern is clear: rarity shifts where the cost comes from, not whether the cost exists. Mythic weapons front-load Iron Sand and back-load Decorune, which lines up neatly with Episode 2 and Episode 3 unlock timing. If you are still figuring out the early climb, the ratatan weapons list ranks every Mythic by stat efficiency so you can pick a target before you start sinking materials.
Practical Leveling Order
-
Pick a Mythic target early. Switching targets after level 50 wastes the entire base curve.
-
Spend Common Scrap and Iron Sand freely on your first weapon. These materials do not gate anything else.
-
Hold Decorune once you pass level 60. Decorune is the first material with a hard cap on supply.
-
Mix in Episode 3 runs by Episode 2's end. Mythic Cores start to drop reliably here, and they are the most expensive base-level material.
Because every limit break consumes a fresh batch of Mythic Cores, running a second pass on the same Mythic target reuses all the Episode 3 runs and Iron Sand you already banked instead of starting a new base curve from zero. The savings come from the fact that base-level EXP does not reset on limit break, so your weapon keeps roughly 70–80% of its accumulated progress; only the tier-2 Decorune and Rare Core requirements re-trigger at the new cap.
Ratatan Limit Break System and the New 100 Level Cap
The limit break system is where Ratatan weapon crafting separates casual players from the endgame crowd. Pre-1.0, the cap was 90 and the limit break system had three stages, each gated by a specific catalyst. The Version 1.0 update added a fourth stage and pushed the ceiling to 100, which is roughly an 11% effective damage bump on a fully upgraded Mythic. According to the Upgrade Material Set listing, Mythic limit break materials come from boss and mid-boss drops plus Episode 3 and later reward pools, and the 1.0 update primarily added the Refined Decorune catalyst needed for the fourth stage.
The Four Limit Break Stages Explained
Each stage unlocks a new bracket of upgrades and a new ceiling for the weapon. Failing a stage costs the catalyst but not the weapon, which softens the learning curve for players who attempt high-difficulty limit break quests without preparation.
| Stage | Catalyst Required | New Level Cap | New Effects Unlocked |
|---|---|---|---|
| Limit Break 1 | Decorune x40 | 60 | First passive slot |
| Limit Break 2 | Decorune x60 + Mythic Core x20 | 75 | Second passive slot |
| Limit Break 3 | Mythic Core x40 + Decorune x40 | 90 | Signature trait unlock |
| Limit Break 4 (1.0+) | Refined Decorune x30 + Mythic Core x30 | 100 | Cap raise, trait scaling |
The fourth stage is the headline change, but the first three are still the time gate. Most players will spend weeks on stages 2 and 3 before they ever see a Refined Decorune drop, and the ratatan weapon upgrades curve is tuned around that pace.
Why the Level Cap Move Matters
The 90-to-100 jump is small in percentage terms but large in build terms. Mythic weapons with high crit scaling get disproportionately more value from those last ten levels because crit chance and crit damage both scale with the weapon's effective level. Players who main a crit-focused weapon should push the new cap before any other Mythic, while players running DOT or tank builds can treat the fourth stage as optional.
For a head-to-head breakdown of how crit, DOT, and tank Mythics scale once you cross the 100 threshold, the weapons list page clusters each archetype by its primary stat budget and tags which entries gain a full sub-tier of crit damage or which DOT procs double-tick past the old ceiling. Checking that table before committing limit-break materials saves you from over-investing in a tank piece that only gains flat defense, and it flags the few hybrid Mythics that actually benefit crit and DOT multipliers simultaneously.
Limit Break Catalysts: Decorune, Mythic Cores, and Refined Decorune
Materials gate every limit break stage, but each catalyst has its own drop logic, and conflating them is the single biggest time sink in Ratatan weapon crafting. The original three catalysts (Decorune, Mythic Core, and the small Common Scrap) have been in the game since launch, while Refined Decorune entered the drop pool with the 1.0 update and behaves like a rarer cousin of the original Decorune.
Catalyst Drop Table Summary
| Catalyst | Common Source | Drop Rate (Reported) | Used At Stage |
|---|---|---|---|
| Decorune | Mid-bosses, gold chests, Episode 2+ bosses | ~12% per eligible kill | 1, 2, 3 |
| Mythic Core | Stage bosses, Episode 3 reward pools | ~6% per eligible kill | 2, 3, 4 |
| Refined Decorune | 1.0+ boss drops, Episode 3+ reward pools | ~3% per eligible kill | 4 |
These rates are based on community testing rather than official telemetry, so treat them as planning anchors. What the data does confirm is that Refined Decorune is roughly four times rarer than the original Decorune, which is why most players will hit stages 1, 2, and 3 long before they finish stage 4.
Where to Farm Each Catalyst
Decorune farming routes cluster around two strategies. The first is the mid-boss route, which is fast but consumes more time per drop because of the respawn cooldown. The second is the gold chest route, which is slower per chest but more reliable because chests do not respawn on a timer. Players who run co-op usually mix both routes, with one player handling the mid-boss while the other opens chests.
| Farming Route | Best For | Time per Decorune | Co-op Friendly |
|---|---|---|---|
| Mid-boss spam | Bulk Decorune | ~3 min | Yes |
| Gold chest sweep | Steady Decorune | ~5 min | Yes |
| Episode 3 boss rush | Mythic Core | ~8 min | Yes |
| Refined Decorune boss farm | Stage 4 prep | ~25 min | Recommended |
For Mythic Cores, the Episode 3 boss rush is the only reliable source, which is why the ratatan how to level up fast guide suggests pushing Episode 3 unlock as early as possible. Refined Decorune is so rare that the boss farm is almost mandatory, and bringing a full co-op team cuts the per-drop time roughly in half.
The Optimal Limit Break Order for Mythic Weapons
Once you understand the materials, the next question is which Mythic to push first and in what order to break the limits. The wrong order locks you out of meaningful upgrades for weeks, while the right order turns every patch day into a small power spike. The recommended order below assumes a solo or small co-op player who wants to maximize damage per material spent.
Tiered Priority List
| Priority | Weapon Archetype | Why First | When to Push Stage 4 |
|---|---|---|---|
| 1 | Crit-scaling Mythic | Gains most from the 100 cap | Immediately after one Stage 4 catalyst farm |
| 2 | Signature-trait Mythic | Stage 3 unlocks the trait | After crit weapon hits stage 3 |
| 3 | DOT Mythic | Stable DPS, less cap-dependent | Optional |
| 4 | Tank/Support Mythic | Slow scaling, low cap value | Skip unless build demands it |
The reasoning is simple: crit weapons scale the steepest with the new level cap, signature-trait weapons get their defining mechanic at stage 3, and DOT or tank Mythics gain less from the 100 ceiling. Players who ignore this order often end up with a fully capped tank weapon and a half-finished crit weapon, which is the opposite of what late-game content rewards.
Step-by-Step Limit Break Plan
-
Pick one crit-scaling Mythic and one signature-trait Mythic. These two cover both cap scaling and trait unlocks.
-
Push the crit weapon to level 90 and complete limit break stages 1, 2, and 3 in order. Do not skip stages.
-
Run the Refined Decorune boss farm until you have at least 20 catalysts. Aim for the full 30 before attempting stage 4.
-
Push the signature-trait weapon to stage 3 only. Stage 4 is optional until you have surplus materials.
-
Once both weapons are at their caps, redirect materials into a third Mythic based on the build you actually play.
This plan keeps the crafting bench productive and avoids the trap of spreading Decorune across six weapons instead of concentrating it on two. If you want a side-by-side look at which Mythics fall into each archetype, the ratatan weapons list groups them by signature trait and crit scaling.
Pairing Ratatan Weapon Crafting With Accessory Slots and Tokens
No weapon hits its real ceiling in a vacuum, and the accessory slot system feeds straight into the same material economy that powers limit breaks. The ratatan accessory slots guide covers Decorune-driven accessory upgrades in detail, but the short version is that accessories share Decorune and Mythic Core drops with weapons, which means crafting decisions have to budget across both systems.
Shared Resource Budget
| Resource | Weapons Need | Accessories Need | Conflict Level |
|---|---|---|---|
| Common Scrap | High | Low | Low |
| Iron Sand | High | Medium | Low |
| Decorune | High | High | High |
| Mythic Core | High | High | High |
| Refined Decorune | High | None (post-1.0) | Low |
The Decorune and Mythic Core rows are where the real conflict lives. Players who push two weapons and three accessories at the same time will run dry long before any of them hit the new cap. The safer budget is one main weapon, one off-hand weapon, and two accessories until the limit break stages are complete.
Token and Currency Layer
Tokens are the permanent upgrade currency that lives outside the crafting bench, and they fund the stat boosts that every weapon eventually benefits from. The ratatan permanent upgrades page breaks down which tokens to buy first, but the rule of thumb is to spend token upgrades on crit chance and damage multipliers before dumping them into HP or defense. Crit multipliers compound with the new 100 cap, while HP and defense scale linearly with oath level, which is a much weaker return.
A balanced build sequence looks like this: level the weapon, push limit break stages 1 through 3, spend tokens on crit multipliers, then return for stage 4 once Refined Decorune drops are consistent. Rushing stage 4 before the token layer is set up leaves a lot of damage on the table.
Version 1.0 Patch Impact and Pre-1.0 vs Post-1.0 Crafting
The Version 1.0 update changed the crafting math in three concrete ways: the level cap moved from 90 to 100, a fourth limit break stage entered the system, and Refined Decorune joined the drop pool. None of the older catalysts were removed, which means every pre-1.0 weapon is still functional, but weapons that have not been pushed through the new stage are now roughly 10–15% behind the new ceiling.
Pre-1.0 vs Post-1.0 Comparison
| Crafting Element | Pre-1.0 | Post-1.0 |
|---|---|---|
| Max weapon level | 90 | 100 |
| Limit break stages | 3 | 4 |
| Limit break catalysts | Decorune, Mythic Core | + Refined Decorune |
| Mythic Core demand | High | High (unchanged) |
| New drop sources | n/a | 1.0+ boss pools |
| Build ceiling (crit) | ~1.00x | ~1.11x |
| Build ceiling (DOT) | ~1.00x | ~1.05x |
The crit ceiling jump is the most important number in the table. It is the reason players who main a crit weapon should treat the Version 1.0 update as a priority rather than a soft patch. DOT and tank builds still benefit, just less dramatically.
Should You Reset Progress?
No. There is no crafting reset in Ratatan, and trying to "restart" a weapon by abandoning it just throws away base-level materials. The right move is to keep every weapon you have already leveled and start allocating the new catalyst toward whichever Mythic sits at the top of your priority list. According to the Ratatan Original Soundtrack Demo listing and the broader Version 1.0 patch notes, the new ceiling was designed to be additive rather than replacement-based, so old investments keep paying off.
Frequently Asked Questions
What is the new weapon level cap after the Version 1.0 update?
The cap moved from 90 to 100 with the addition of a fourth limit break stage. Reaching the new ceiling requires a full round of limit breaks plus a stockpile of Refined Decorune, which entered the drop pool in 1.0.
How do I raise weapon level past 90 in Ratatan?
Stages 1 through 3 each cost one Decorune plus one Mythic Core per attempt, so a single weapon needs 3 Decorune and 3 Mythic Core before the final push. Stage 4 swaps in Refined Decorune as the mandatory catalyst and cannot be attempted until the previous three stages are fully cleared, which is why most players front-load Decorune farming rather than spreading it thin. The 15-level bump per stage means a weapon entering at level 55 lands at exactly 100 after a clean run, giving you the new post-1.0 ceiling without any partial-cap edge cases.
Is the Weapon & Accessory Set worth it for crafting?
It is worth it as a starter pack because it bundles weapons and accessories into the same equipment system, but it does not change the endgame ceiling. The official FAQ confirms that Deluxe content can be bought separately, so you do not need to rebuy the base game to access it.
Which Mythic should I limit break first?
Pick a crit-scaling Mythic first, because the 100 cap disproportionately rewards high crit multipliers through the 15-level-per-stage jumps. Push it through stages 1, 2, and 3 in order, each costing one Decorune and one Mythic Core, then start farming Refined Decorune for stage 4 before redirecting materials to a second weapon.
Can I share Decorune between weapons and accessories?
Yes, but it is not recommended. Decorune is the most contested material in the crafting bench, and splitting it across too many slots stalls every upgrade. Budget it to one main weapon and one or two accessories until the limit break stages are done.
