DELTARUNE Fight Wiki — Boss Guides, Tier List & Tips

Play the earliest boss first and treat it as a tutorial rather than a challenge. Learn the three core inputs before anything else: the confirm key advances menus and dialogue, the back key cancels or retreats, and the third input changes meaning depending on the encounter. Watch the cursor instead of your own character, because damage is avoided by moving that cursor through gaps in the pattern. Repeat one fight until the tells are memorised rather than spreading attempts across the roster, and bank a clean survival before trying to attack. Muscle memory carries over between bosses far better than raw reaction speed does.

The roster is still growing, so any fixed count goes stale quickly. Community coverage as of the September 2026 build documents King, Pink, Tenna, Jevil and a Kaizo-style Knight remix, with new fights having arrived one update at a time since launch. Because content is added in waves rather than in a single drop, a boss that did not exist a month ago may already be in the game. Check the update log before assuming a fight is missing, and treat any list you find as a snapshot of the current version rather than a finished roster.

The Kaizo-style Knight remix sits at the top of most community rankings. It reworks the standard Knight encounter with tightened dodge windows and far less recovery between patterns, and clearing it is treated as a completion milestone rather than a routine fight. Below it, the television-themed boss is widely described as the hardest of the standard encounters because its rotation is long and its second phase punishes late reads. Rankings do shift between updates, since a balance pass can widen a window or add a pattern, so use the tier list as a working model and re-check it after each patch.

Both raise the pressure without inflating boss health, but Genocide goes further. Brutal increases attack density and noticeably shrinks the safe gaps between patterns, which is the tier most community clear videos use for boss showcases. Genocide is the hardest documented tier in the current build: rotations run longer, dodge windows are very small, and clears tend to be recorded per boss rather than as a full run. Difficulty is selected per encounter too, so you can keep a comfortable clear on one boss while pushing Genocide on another without resetting your whole save.

Yes, though it is found through play rather than advertised on the game page. The clearest example is the Kaizo-style Knight remix, a harder variant that sits outside the standard ladder and functions as optional endgame content. Progression also gates part of the roster: additional fighters and encounters unlock alongside clears instead of through a shop, so unlocking content generally means beating what you already have. Because new fights arrive one update at a time, hidden content is best tracked by following the update log and community clear videos rather than a single static list.

Yes. Each server supports up to fifteen players, which is enough for a group to spread a single attack rotation across several people instead of one player reading the whole pattern. Bringing a group matters most on Brutal and Genocide tiers, where one player drawing off part of a pattern buys everyone else a safe window to reposition. The game also runs on mobile, console and desktop from the same place, so friends are not locked to one platform. If a session feels desynced, check your connection first, since cursor movement is continuous and even small amounts of lag show up as unfair-looking hits.

No. DELTARUNE Fight does not run a redemption-code system, and the game page lists no code entry feature, no paid passes and no badge rewards. Any site advertising working codes for this game is either referring to a different Roblox Deltarune project or inventing them outright, which is a common problem because several similarly named fan games exist. Progression comes from clearing fights and unlocking content through play, not from entering strings. If that ever changes we will document the real codes here with the source and date they were verified, and we will not publish unverified ones.
