Well Dweller All Bosses: The Full 15-Boss Roster in Fight Order

A quick heads-up before the roster: this page names every encounter from the opening area through the endgame, so if you want a clean first meeting with each boss, bookmark the page and only scroll as far as you have progressed.

How was this boss list put together?

The roster comes from a complete, chaptered fight recording by the channel Zhain Gaming (embedded at the bottom of this page), which captures every encounter on a single playthrough from the Dark Garden to the late-game areas. Chapter order on that video matches the order a normal route meets each boss, so the list doubles as a progress map: stuck on entry five means you are roughly a third of the way through the campaign.

Two honest caveats. First, this is a metroidvania, and side-area exploration can shift when some encounters happen for you. Second, the list covers what community footage shows — it is not an official claim that no other fight exists anywhere in the kingdom.

What are all 15 bosses, in fight order?

Which encounters deserve a closer look?

The Groundskeeper (1) opens the game’s boss run in the Dark Garden, where a gravestone for the kingdom’s gardener sits “outlived by his own work.” It hits noticeably hard for a first fight, which is exactly why it has its own dedicated guide.

The Hunter (2) is the figure from the intro who bagged Glimmer’s siblings, and the fight at the hunter’s cabin carries that weight. Players who tried the demo will recognize it: the demo build ended here, so this is many people’s first real mastery test.

Lady Of The Drains (4) arrives in the kingdom’s drains, and her gravestone text does the storytelling: the body of a witch banished below, who “stole the young with candied lures.” One streamer nicknamed her the elevator boss for how the arena moves, and footage shows her attacks sweeping at angles that are easy to misread.

Lida The Terrible (5) carries a spelling warning. Full-fight videos title her “Lida The Terrible,” while the official store page spells the mouse character Ilda, and transcript captions render the boss announcement as something closer to “leader the terrible.” The sideshow-style introduction describes a witch “from the fiery pits of hell” who tried to swallow a townsman whole — but whether that witch and the friendly mouse share a name is unconfirmed, so treat the spelling as unsettled.

The Queen (6) is preceded by an “evade the queen” objective through her own castle, a stealth-flavored gauntlet rather than a straight brawl. The false queen who took the throne after the old queen died is the story’s central villain, and this first phase is the game’s midpoint statement.

Starsinger (9) leaves behind one of the best epitaphs in the game: a restless young watchman whose beautiful song tricked a hunter to his death. Expect the fight to lean on that lure motif.

Forest King (10) is the oddest entry on the list, because community footage plays it as a tribute quest — present a remarkable acorn, “win over the forest king,” and receive a golden feather. Whether it can turn hostile is not shown in the footage we checked, so treat the encounter as puzzle-flavored rather than a pure brawl.

Silver Doll (15) closes the roster as “a metal doll in likeness with the queen which shared both her resemblance and her temper” — a fittingly sour note for the final act.

Does the boss order ever change?

Mostly no, with a caveat. The early route is linear enough that encounters one through six land in the same order for nearly everyone, and the chaptered fight video matches the sequence most players report. Deeper in, the game opens up: areas like the shrine, the inn, and the dollmaker’s stretch can be approached in slightly different orders depending on how much optional exploration you do, so do not panic if your personal ordering of entries 11 through 14 differs a little.

Where should a new player go next?

If you are early in the run, the beginner guide covers the opening loop, and the matchstick guide explains the flame system every boss fight runs on. Before a hard wall, it is worth reviewing how trinkets reshape a build, because the right loadout often matters more than raw health. And if you want to know whether the whole hunt is worth your evening, our review-style breakdown covers the case for and against.
