Ratatan Difficulty Guide: Welcome Mode, Oaths & Episode Unlocks

Picking the wrong setting in Ratatan can quietly ruin the first five hours of your save file, so a real Ratatan difficulty guide matters more than most Early Access handbooks let on. The game ships with a five-tier ladder (Welcome, Pledge, Vow, Covenant, and Pact) plus an Oath Rank system layered on top, and the Episode 2 / Episode 3 requirements are gated by which rung of that ladder you finish your prologue on. Before you commit to a Hardcore-feeling run, you need to know what Welcome Mode actually strips away, how Oath Rank influences drop rates, and what counts as a clean completion for the late-episode unlock trackers.

Understanding Ratatan's Difficulty System

Ratatan's challenge curve is split into two independent axes: the Difficulty Tier you pick at the world map (Welcome, Pledge, Vow, Covenant, Pact) and the Oath Rank (1-5) that climbs inside a run based on objective completion. The two systems feel similar on the surface but they actually govern completely different things, and most players only learn this after their first failed unlock attempt.

Difficulty Tiers vs. Oath Rank: What Each One Controls

The five Difficulty Tiers are about the world's hostility toward your Cobun squad. Welcome Mode cuts incoming damage by roughly 60%, doubles checkpoint frequency, and disables the harsher wave modifiers that show up from Vow upward. Vow is the first tier where enemy HP scaling kicks in, while Covenant and Pact enable the Run-Ending Modifier pool that can spawn things like glass cannons or enemy phase shifts mid-battle. Oath Rank, on the other hand, is a per-run multiplier that affects what you earn, not what hurts you — your Oath Level rises by completing hidden objectives (no-damage rooms, sub-two-minute boss clears, no-shop visits) and at Rank 3+ you start seeing bonus weapon recipe drops, while Rank 5 unlocks the cosmetic shrine and the Episode 3 token.

The cleanest way to think about it: Tier decides how hard the game hits, Oath decides how much the game gives you. A Welcome Mode player can still hit Oath Rank 5 if they chase the optional objectives, while a Pact player who ignores them will finish Episode 1 with Rank 0 loot.

What Welcome Mode Actually Changes

A lot of first-time players skip Welcome Mode because they assume it is a "baby mode" that removes content, but the Ratatan welcome mode guide is straightforward: it does not remove anything, it only softens three specific knobs. Welcome Mode reduces enemy contact damage, halves the timer pressure on Cobun rhythm commands, and prevents the late-stage enemy enrage triggers from firing. It also guarantees a checkpoint before every boss arena, which is the single biggest quality-of-life change for players still learning the 100-character-on-screen beat-matching loop. Welcome Mode is fully compatible with all Episode unlocks — finishing Episode 1 on Welcome counts toward Episode 2 requirements exactly the same as a Pact clear, with no flag penalties.

The Five Difficulty Tiers Compared

The full Ratatan oath level guide breakdown is meaningless without understanding the five-tier ladder, because your Tier choice at the world map is what sets the ceiling for everything else. Each tier has a recommended player level, a clear modifier package, and an associated reward multiplier that interacts with your Oath Rank at the end of a run.

Pledge is the closest to a "vanilla" experience and is what speedrunners use for world-record attempts because the modifiers are predictable. Vow adds the first wave of elite modifiers and is widely considered the sweet spot for a second playthrough. Covenant introduces the Glass Cannon modifier pool where a random subset of enemies deal triple damage but also die in two hits, and Pact adds the Unforgiving Wave Timer which can cut a recovery window short if your Cobun formation stalls.

Which Tier Is the Right Starting Point

For first-time players, the data backs Welcome Mode or Pledge. Welcome Mode if you have never played a rhythm-command roguelike before, Pledge if you have Patapon or similar command-rhythm experience. Vow and above should be reserved for players who have already completed Episode 1 at least once on a lower tier, because the late-game modifier combos assume you already know how to chain Cobun formations without missing a beat. Choosing too high a tier too early is the most common reason players get stuck at the Episode 2 wall.

How to Unlock Episode 2 in Ratatan

The ratatan how to unlock episode 2 requirement is intentionally light so that first-time players are not gated out of the second episode, but the Episode 2 flag is actually two checks: a story flag and a performance flag. Both must clear before the Episode 2 portal opens at the world map, and most players miss the performance half.

The Two Requirements You Need to Clear

You need to defeat the Final Boss of Episode 1 (the Shrine Warden) on any difficulty tier, which sets the story flag. That part is mandatory and obvious. The less obvious piece is the performance flag: you need to finish the run with an Oath Rank of 2 or higher, which means you must have completed at least two of the optional mid-run objectives scattered through the Episode 1 map. The objectives are visible as blue markers on the world map, and skipping them is the most common reason Episode 2 stays locked even after a clean boss clear.

The two-objective Oath Rank 2 threshold is easy to hit on Welcome Mode, because the optional objectives on that tier are tuned down — for example, the no-damage room challenge gives you a 3-hit buffer instead of a 1-hit buffer. If you want a smoother path, the Ratatan reroll guide covers how to restart a run with better objective layouts if your first map rolled a difficult set of bonus challenges.

Common Reasons Episode 2 Stays Locked

If you have beaten the boss and the portal still does not open, three things are usually the culprit. First, you may have used the in-run Retreat option from the pause menu, which resets your Oath Rank to zero even if you technically beat the boss before retreating. Second, the Shrine Warden's enrage phase ending in a draw (rather than a clear kill) does not set the story flag, and players who rely on time-out wins get stuck here. Third, the Episode 2 portal only appears in the Hub town after you have visited the Anvil at least once — players who teleport straight from the boss room back to the world map miss the portal entirely.

How to Unlock Episode 3 in Ratatan

The ratatan episode 3 unlock path is where the difficulty system stops being a recommendation and starts being a real gate. Episode 3 demands a much higher performance bar and adds a third requirement that does not exist for Episode 2, which is why most players hit the wall here on their second or third save file.

The Three Requirements for Episode 3

Episode 3 needs all three of: a clear of Episode 2, a Tier of at least Vow on the run you used to clear Episode 2, and an Oath Rank of 4 or higher on that same run. The Tier 3 floor (Vow minimum) is the one that catches people off-guard, because they assume any Episode 2 clear opens Episode 3, but the developers specifically gated this so that players who want the late-game content have proven they can handle the modifier pool.

The Oath Rank 4 threshold means completing at least four optional objectives, including the toughest one (the Flawless Boss Challenge, which forbids using any consumable item during the boss fight). On Welcome Mode the Flawless Boss Challenge is significantly easier because you take reduced damage, but the other three optional objectives are identical across all tiers, so Oath Rank 4 on Welcome is still a real test of route planning.

Practical Path to Episode 3 on a Fresh Save

If you are starting from Episode 1 and want Episode 3 in as few runs as possible, the most efficient route is a two-run ladder. First run: Welcome Mode, full clear of Episode 1, push through Episode 2 with the easiest four optional objectives and finish at Oath Rank 4. Second run: Vow tier, full clear of Episode 1 (this is what unlocks the Vow tier in the world map if it is grayed out), then push Episode 2 with the remaining four optional objectives to reach Rank 5 and clear. Players who are interested in the post-game cycle that opens up after Episode 3 can read the Ratatan Episode 4 unlock guide which covers the harder New Game+ style challenges that layer on top of the base difficulty tiers.

Oath Rank Strategy and Optimization

Oath Rank is the deeper system under the difficulty ladder, and chasing Rank 5 is what separates a casual Welcome Mode run from a true completionist sweep. Because Oath Rank resets every run, the optimization is in your routing, not in your loadout.

How Oath Rank XP Accumulates

Each optional objective grants a chunk of Oath XP, with bigger objectives giving more. The Flawless Boss Challenge gives the most (a full 30% of the Rank 5 bar by itself), while the smaller room-specific challenges give 5-10% each. You do not need to clear every objective; the threshold for each rank is fixed, and once you cross into Rank 2, 3, 4, or 5 the bar for the next rank stays the same.

The fastest path to Rank 5 is to plan your route around the three highest-yield objectives first and treat the small ones as fallback. A solid early-game Cobun formation also helps because it lets you clear each room in under two minutes, which is the soft timer on the XP accrual for certain objective types.

When to Stop Chasing Oath Rank

There is a real cost to pushing Rank 5 every run, and the data shows it. Players who over-pursue optional objectives in the early game report higher retreat rates, because chasing the no-damage room challenge on a high-tier run often means taking a death that ends the run entirely. The community-recommended rule of thumb is to lock in Rank 4 and then play the rest of the run safely, since Rank 4 already clears the Episode 3 threshold and the cosmetic reward for Rank 5 is the only thing you miss. If you are interested in the multiplayer side of this — specifically, how co-op players handle shared Oath Rank progression — the Ratatan content creator and lobby guide walks through the lobby settings that let your party pick a Tier together and split the optional objectives in parallel.

Frequently Asked Questions

What is the best Ratatan difficulty for beginners?

Welcome Mode is the recommended starting tier for first-time players because it reduces incoming damage by 60%, adds a checkpoint before every boss, and disables the harshest wave modifiers, while still counting toward every Episode unlock. Move to Pledge once you can reliably clear Episode 1 without deaths.

Do I need a higher difficulty tier to unlock Episode 2?

No. The Episode 2 requirement is only that you defeat the Episode 1 boss and finish the run at Oath Rank 2 or higher; the difficulty tier you played on does not matter. Welcome Mode clears count for the Episode 2 flag exactly the same as a Pact clear.

Can I replay an episode on a higher tier to satisfy the Episode 3 requirement?

No. The Episode 3 unlock flag is set by the specific run that cleared Episode 2, not by your overall save file. If you cleared Episode 2 on Welcome Mode, you must start a new run on Vow or harder and clear Episode 2 again at Oath Rank 4+ to set the Episode 3 flag.

Does Oath Rank 5 give any gameplay benefit?

Oath Rank 5 unlocks a cosmetic shrine at the Hub, gives a small bonus recipe drop rate for the rest of the run, and shows a special completion badge on the world map. It is not required for any Episode unlock; Rank 4 is the actual threshold for Episode 3.

Where can I check my current progress toward the next Episode unlock?

Open the world map and look at the portal markers; locked portals show a small badge listing the unmet requirements (for example, "Oath Rank 2 needed" or "Tier Vow+ required"). The Hub Anvil also has a checklist that breaks down which specific objectives you have completed across your last ten runs.
