Deliria Boss Rankings

Linesway markets nine bosses — nine Lovecraftian gods — plus hundreds of ordinary nightmares between them. This page ranks only names we can source. It is a prep ranking from playtest HUD text and the first Steam build, not a cleared bestiary and not a patched meta. Pair it with the boss walkthrough for movement notes and with combat for style rank, including the climb to SSS.

Deliria is on Steam (app 3725650). The store date is listed as 2 September 2026. Blood Moon and Hastur’s Invasion are the two invasions, not extra rows on the nine-god chart. They still use the same swords, guns, bows, and magic loop, so a boss grade that ignores night defense is incomplete.

Return to the tier list hub for weapons and biomes, or to getting started if you do not yet have tools. Soundtrack titles such as Yoggoth, Cerebral Excoriator, Petry, Lord of Goo, The Eye of Deliria, Wyrm of the Barrens, The Great Pathogen, and SUPERSTRUCTURE are OST names. They are not a confirmed extra roster.

How this list is graded

S means public footage plus a HUD or chat string, and the fight clearly punishes a bad plan. A means we saw a full or near-full attempt and can warn you. B means the name exists in playtest with too little kit shown to pretend we know the phase list. Unranked is the honest bucket for the five unpublished gods.

We do not invent extra named bosses to fill a nine-row table. Fan nicknames stay off this chart until the game prints them on screen. Early Steam sessions can still softlock or dump you through terrain; that is a install checklist problem, not a hidden phase. Buy-night opinions sit on the review.

Co-op changes every grade. Steam lists online and LAN co-op plus PvP. Yoggoth’s playtest used a team spawn. A solo rank for that fight is a guess dressed as a letter. Creative mode can even put bosses on opposite teams; that is a sandbox toy, not a substitute for surviving the real summon.

S — Eye of Deliria

The HUD calls it Eye of Deliria: a flying fiery skull-beast. It is the encounter marketing and screenshots lean on, and it is the one that most obviously tests 3D movement. You cannot treat a hovering skull like a ground slime. Vertical space, mounts, and any flight you unlock later all matter more here than on Prince Petry. Grapple and wings, listed on the store, are the movement verbs that make this S row honest.

Style rank wants a clean chain. A flying target that weaves is a gift if you mix melee and guns, and a wipe if you stand still. Read controls so camera and jump are not fighting you mid-air. If you practice in a carved pit, the building guide covers arenas; a roof can trap you under a flyer. Do not summon this on a frozen ridge with no cover — check the biome rankings first.

A — Yoggoth

Playtest chat printed “Yoggoth Has Awoken!” when the fight started. The encounter used a team spawn, which is the clearest hint that Linesway expects more than one body in the arena. In that same clip the kill came from ShotCopperBullet, a named gun-side tool, not a heroic last swing of a copper sword.

That is why Yoggoth sits in A: ranged pressure is proven; melee-only is not. If you are learning guns, skim the weapon rankings before you spend ore on a vanity blade. Co-op defenders should read multiplayer so partners share the spawn instead of wandering a different cave. Hosts who leave PvP on will turn a team spawn into a grief clip; leave it off until the god is dead.

A — Prince Petry (Petri)

Playtest treated Prince Petry as a slime-prince comparison: a royal blob with guards that obey him. Some chat spelled it Petri. The practical lesson was spacing. Commentators called melee a bad idea on Petry specifically, while noting other fights might tolerate close work. Keep distance. Bows, knives at range, and patience beat a greedy hammer swing.

Dynamite showed up as a joke option and a self-kill. Do not rank explosives as a Petry strategy. After the crown dropped, gold from the kill was enough to start shopping for residents — which is why this boss also feeds the NPC housing loop. A first-week plan can be: survive Petry at range, cash out, raise a house, then think about Eye of Deliria. The OST track Petry, Lord of Goo is flavor, not a second prince.

B — Leapus (Lepus)

Leapus appeared in playtest; some strings use Lepus. There is not enough public kit to pretend we know hop patterns or a weak point. B-tier here means named and real, not “easy.” Treat it as a calendar item until more players publish a full fight. Do not fill the gap with a soundtrack nickname.

Unranked — five of nine gods

Steam and trailers still sell nine bosses. Four names are confirmed above. The remaining five stay blank on this wiki. Filling those slots with invented titles would poison every other page. When Linesway prints a fifth HUD name, it will get a letter here and a section on the bosses guide. Until then, budget gear and ore for the four we can study. The roadmap is explicit: shipped pitch is nine gods; shipped names are four.

Invasions can feel like bosses. They are not substitutes for the nine. Hold the town with building and armed residents, then go hunting gods in daylight. Climate still matters: blight and Lovecraftian or evil biomes are poor places to stand while you learn a new HUD bar. English-only UI means every wake message will be English, including Yoggoth’s line. There are no promo codes that skip a god, and Deliria is not a Roblox title with a secret S-tier script.

The 71 Steam achievements and the Necronomicon will nag you toward gaps. Let them. Do not let a blank row become a fan-named raid. Drill Eye of Deliria movement and Petry spacing. Leave blank rows blank instead of decorating them with fake god names.
