Our boss index covers ten named fights: Ain, Enma, Irbes, Kurtz, Mirkam, Nagaraja, Ortrinde, Saitin, Sommar, and Sorron. Several bosses named by players and the competitor write-ups are not in our wiki yet. This page lists them, sketches the location and story role the source pack hints at, and explicitly flags where the spelling or placement is uncertain.
For the confirmed roster, see the boss index. For region-by-region context, see the region guides. For the 1.0.38 hotfix that introduced two of these names, see 1.0.38 hotfix notes.
Missing Boss Roster
| Boss | Region / Location | Story Role | Verified In Our Pack? |
|---|---|---|---|
| Resio & Fatum | Dual fight; location unverified in our pack | Named as a pair boss in competitor write-ups | No |
| Giant Guardian | Mid-area facility (likely Kannir Belt or related); placement unverified | Facility-style mid-boss | No |
| Damaged Eradicator | Story boss linked to Eradicator | Story beat in the protagonist’s route | No |
| Eradicator | Region unknown in our pack | Pairs with the Damaged variant | No |
| Odz | Tuned in the 1.0.38 hotfix alongside Kurtz and Sorron | Late-game antagonist candidate | Yes (1.0.38) |
| Murant | Tuned in the 1.0.38 hotfix | Late-game antagonist candidate | Yes (1.0.38) |
| Saemo | Region unverified | Named in community walkthroughs | No |
| Infected Carbo | Infection-state variant, tied to Carbo | Story-state fight during a Nia infection arc | No |
The two rows confirmed in our own content pack — Odz and Murant — appear in the 1.0.38 hotfix notes under “Boss Tuning”, where the patch text describes them as new fights without naming an arena.
Story And Route Sketch
Because the source pack is thin on most of these fights, treat the bullet points below as a working hypothesis built from the patch notes, the Endings guide, and the competitor fatalclaw-wiki.wiki roster.
- Resio & Fatum. A dual encounter — typically means two arenas you must juggle, or a single arena with split threat lanes. The pair format tends to favor Cabitz setups that can answer two telegraph sets at once.
- Giant Guardian. A facility boss. If it lives in Kannir Belt or a connected mechanical space, the relevant counters are positioning tools — Blink, Lyani’s Claws, and patience with Kannium spend on the Claw tree.
- Damaged Eradicator and Eradicator. These read as a story pair. The damaged variant is likely a first encounter; Eradicator is the cleaner version later in the route. Cross-reference any future encounter with the Endings guide because the corruption thread runs into the late-game story beats.
- Odz and Murant. Tuned in 1.0.38 alongside Kurtz and Sorron. Their inclusion in the tuning list suggests they sit at the late-game difficulty tier, where Cabitz preparation and route-state checks matter more than raw execution.
- Saemo. Region unknown. If the name lands in a future patch text or content-pack revision, route placement will be straightforward to map.
- Infected Carbo. The infection framing matches the Nia infection sequence updated in the 1.0.38 hotfix, where villagers Jack, Mark, and Rotri gained infection-state expressions. A boss with “Infected” in the name likely triggers during or just after a similar narrative beat.
Cross-Links To Confirmed Content
Each row above should eventually link to a region page once the location is verified. Until then, the safest cross-references in our wiki are:
- Kannir Belt region guide — facility-context candidate for a Giant Guardian placement.
- Higasha Tundra region guide — late-region candidate.
- Aphotic Marsh region guide — late-region candidate where Silver Chain enters the route.
- Sealed Spire region guide — late-route destination; many story bosses converge here.
- Elord Castle region guide — Act 1 hub; some story bosses gate the castle return.
Honest Gaps
- Spelling and romanization vary by source. The competitor fatalclaw-wiki.wiki and fatal-claw.wiki do not always agree on the same name for the same fight. Ours uses the spellings confirmed in our content pack (Odz, Murant); the others here are best-effort transcriptions and may shift in a future source-pack update.
- Region placement is unverified for six of the eight entries. A region link in this page would be invented. Mark this section as a working sketch rather than a guide.
- Attack patterns are unknown. We do not publish invented phase tables. Each row here is a placeholder until the boss index gains a dedicated page or a future hotfix names the fights directly.
- Story order is implied, not confirmed. The ordering implied above comes from the 1.0.38 tuning list and the Endings guide storyline. Treat it as a hypothesis.
When a future source-pack revision names any of these fights directly, this page will become the hub for individual boss pages rather than a roster.
