Sephiria Costumes Unlock Guide - All 27 Costumes Explained
How the Sephiria costumes unlock system works: the 27-costume roster, unlock condition types, the Bat character, and why abilities make costumes matter.
How Sephiria’s Costume System Works
Sephiria contains 27 costumes in total: 8 available by default and 19 that must be unlocked through play. Costumes are not simple cosmetic swaps. Each one comes with its own ability, which means your choice of costume changes how a run plays, not just how it looks. In a game where builds, grid synergies, and weapon choice already define your run, the costume is one more lever, and often a meaningful one, over your starting conditions and power curve.
Because costumes carry abilities, the unlock system doubles as long-term progression. Every costume you add to your collection is another tool for specific situations: one might suit a hard mode tier push, another a particular weapon, another a first-clear attempt. The 8 default costumes give you a workable range from the start, but the 19 unlockables are where the system opens up.
| Costume Group | Count | How You Get Them |
|---|---|---|
| Default costumes | 8 | Available from your first run, no conditions |
| Unlockable costumes | 19 | Earned via milestones, secrets, quests, and challenges |
| Total roster | 27 | The full collection tracked in game |
Why Costumes Matter More Than Skins
In many action games, costumes are rewards you wear after the real decisions are made. Sephiria treats them closer to loadout choices. A costume’s ability interacts with everything else you do in a run: the weapon you main, the way you arrange your inventory grid, the adjacent slate reinforcement buffs you chase, and the talismans and artifacts you pick up on the way down. Two players running the same weapon with different costumes can end up with noticeably different runs.
That is also why this guide will not tell you that some specific costume is unconditionally best. Ability value depends on context: a costume ability that shines in a Greatsword hard mode push may be mediocre for a Crossbow learning run. The right approach is to unlock broadly, read each ability carefully, and match costume to plan rather than wearing whatever you unlocked most recently.
The Types of Unlock Conditions
Sephiria does not gate its 19 unlockable costumes behind a single kind of task, which is part of what keeps collection interesting across a long playthrough. Rather than list conditions costume by costume, which is better discovered in game, it helps to understand the categories the unlock conditions fall into.
| Unlock Category | What It Generally Involves | When You Encounter It |
|---|---|---|
| Progression milestones | Advancing the core game: clearing tower sections, pushing difficulty tiers | Naturally, as you play |
| Exploration and secrets | Finding hidden rooms, out-of-the-way areas, and tucked-away interactions | When you explore floors thoroughly |
| Quests and NPC storylines | Following specific characters’ quest lines, including the Elru quest chain | When you talk to NPCs and accept quests |
| Special challenges | Performing specific feats or meeting unusual conditions during runs | When you experiment and retry |
| The Bat character | A well-known unlock with a dedicated method the community documents | When you follow the known steps |
A few patterns are worth internalizing. Progression-based unlocks take care of themselves if you simply keep playing and pushing tiers, so they never need a dedicated hunt. Secret and quest-based unlocks reward players who sweep every floor and talk to every NPC, which is good hygiene anyway. Challenge-style unlocks are the ones that demand deliberate attempts, and those are also where community guides and videos are most useful, since the conditions can be specific enough that finding them blind is unlikely.
The Bat Character: a Worked Example
The clearest illustration of how specific unlock methods can be is the Bat character. The Bat is unlocked through a known, deliberate method rather than passively through normal progression, and it has become one of the most commonly asked-about unlocks in the community. Multiple videos titled along the lines of “How to Unlock the Bat Character in Sephiria” walk through the steps, which tells you two useful things.
First, some unlocks in this game are specific enough that looking them up saves real time; there is no shame in consulting a guide for the Bat or any other stubborn costume. Second, the existence of dedicated unlock videos signals the health of the collection system: players care enough about the full 27-costume roster to document individual unlocks. If you get stuck on any costume, searching for its name plus “unlock” will usually surface a current, post-1.0 walkthrough.
Tracking Your Progress In Game
You do not have to keep a spreadsheet to know where you stand. Sephiria provides in-game tracking for costume unlocks, and the costume shop in town is the natural hub for seeing what you own, what remains locked, and what information the game gives you about locked costumes. Make a habit of checking it between runs.
A practical collection routine looks like this: after each session, glance at the locked costumes and note whether anything new shows a hint or condition you now recognize. When a hint corresponds to something you nearly did in your last run, you have a ready-made goal for the next one. Collecting costumes this way, a goal or two at a time, keeps the 19 unlockables feeling like a steady drip of new toys rather than an intimidating checklist. And because each costume adds an ability, every unlock genuinely changes your options instead of just incrementing a counter.
Costumes and the Rest of Your Progression
Costumes sit inside a wider progression system that includes talent points, weapon unlocks, and permanent upgrades between runs. They compound. A new costume can make a weapon you had written off feel strong, or give a hard mode push the specific edge it was missing. Conversely, deeper talent investment makes costume abilities more reliable. When you plan what to do next in Sephiria, treat costumes as part of your build planning, not as a side collection, and the 27-costume roster becomes one of the game’s main long-term motors.
