You’ve probably been there. You are tearing through the Anchordeep, feeling like a literal god of death. Your fleece is glowing, your followers are praying, and your sword is swinging with enough force to level a mountain. Then you hit the door. The music shifts. The water ripples. Cult of the Lamb Kallamar floats into the center of the arena, and suddenly, that "god" feeling evaporates into a mist of frantic rolling and panic.
Kallamar isn't just another boss. Honestly, he’s a massive difficulty spike that catches people off guard because he plays by different rules than Heket or Leshy. While the earlier Bishops of the Old Faith focus on telegraphed slams or predictable minion spawns, Kallamar is a bullet-hell nightmare. He represents the cowardice of the pantheon, but his cowardice makes him the most dangerous thing in the game. He's terrified of you. And because he's terrified, he throws everything—fireballs, rings of light, explosive projectiles—at the screen at once.
It's a chaotic mess. It’s brilliant. It’s also the point where many players realize their build is actually terrible.
The Cowardly Bishop of Anchordeep
In the lore of Massive Monster’s hit, Kallamar is the third Bishop you’re supposed to take down. He rules over Anchordeep, a soggy, bioluminescent purgatory filled with explosive jellyfish and annoying armored flies. If you pay attention to the dialogue, you’ll notice Kallamar is the only one who sounds genuinely shook. He’s the "Bishop of Famine," but he’s also the Bishop of "Please don't kill me."
He begs. He bargains. He tries to convince the Lamb to just go away. This cowardice isn't just fluff; it translates directly into his boss mechanics. Unlike Shamura, who fights with a sort of elegant, tragic madness, Kallamar fights like a cornered animal with a machine gun. He keeps his distance. He teleports. He summons waves of enemies to do the dirty work while he pelts you with rings of fire from the margins.
The design is deliberate. Anchordeep is claustrophobic, and the boss fight reflects that by filling every available pixel of space with something that wants to hurt you. If you go in expecting a melee brawl, you’re going to have a bad time.

Why the Cult of the Lamb Kallamar Fight Breaks Most Players
Let’s talk about the projectiles. Most bosses in Cult of the Lamb have a rhythm. You dodge, you hit twice, you dodge again. Kallamar doesn't care about your rhythm. He has an attack where he fires a circular spray of fireballs that expand outward. While that’s happening, he might also swing his sword or summon a swarm of those annoying blue squids.
It’s the overlap that kills you.
- The Sword Swing: It has a massive arc. If you’re greedy with your hits, you’ll get clipped.
- The Ring Fire: These move at different speeds. Some linger.
- The Minions: They aren't just distractions; they are roadblocks that stop you from rolling out of the way of the big stuff.
If you are playing on "Hard" or "Extra Hard" (and heaven help you if you’re doing a Permadeath run), Kallamar is often the run-ender. You can’t just out-damage him if you can’t get close. This is where your choice of Curse becomes more important than your actual weapon. If you don't have a long-range option, you are basically playing a game of "Don't Touch the Lava" while someone throws rocks at your head.
Strategies That Actually Work (And Some That Don't)
Most people try to rush him. Don't do that. Kallamar punishes aggression. If you try to stick to him like glue, he’ll just teleport and leave you standing in a pile of bombs.
Instead, focus on the Curses. The Divine Blast is okay for clearing some space, but what you really want is something like the Hounds of Fate or any of the projectile Curses that track. Being able to deal damage while you are busy dodging a hundred fireballs is the only way to keep your sanity.

Watch the sword. Kallamar has a tell before he swings. He pulls back slightly. Most players miss this because they are staring at the thirty fireballs on the other side of the screen. If you can parry (if you have the right cards), you can turn the tide, but for most of us, it’s about that frame-perfect roll.
Another thing: clear the minions immediately. It’s tempting to ignore them and focus on the Bishop, but the squids will eventually corner you. One hit from a squid staggers you just long enough for Kallamar’s projectile ring to finish the job. It’s a combo that has ended more "Perfect Boss" attempts than almost anything else in the game.
The Post-Game Rematch: Kallamar in Purgatory
If you thought the base fight was annoying, the post-game version in the Relics of the Old Faith update is a whole different beast. He gets faster. The patterns get tighter. By this point, you should have access to Relics, which are the absolute game-changer for this encounter.
Using a Relic that freezes time or grants temporary invincibility is almost mandatory here. The Eye of Hephaestus or anything that triggers on a roll can help chip away at his health while you’re focused on survival.
Interestingly, many players find Kallamar harder than the final boss or Shamura. It’s a specific type of difficulty. It’s "bullet hell" difficulty in a game that is otherwise an action-roguelike. That's why he sticks in people's minds. He forces you to change how you play. You have to stop being a brawler and start being a dancer.

There is a certain satisfaction in finally pinning Kallamar down. When his health bar finally hits zero and he does that dramatic, exploding animation, the relief is palpable. He’s the hurdle. If you can beat Kallamar, you can beat the game.
He also serves as a great narrative foil. While the other Bishops are stoic or angry, Kallamar’s desperation makes him feel more "human" in a weird, eldritch way. He knows what’s coming. He knows the Lamb is an unstoppable force of nature, and his frantic, messy combat style is a perfect reflection of a god who knows he’s about to be replaced.
Actionable Steps for Your Next Run
If you’re currently stuck on this multi-eyed nightmare, here is exactly what you should do before you enter Anchordeep again:
- Prioritize Fervor Generation: You need your Curses. Take any Tarot card that drops more Fervor or allows you to use Curses more cheaply. You won't win this with a slow hammer.
- Hunt for the Golden Fleece: If you are confident in your dodging, the Golden Fleece can make this fight trivial by boosting your damage to insane levels. But be warned: one hit and you’re back to square one.
- Use the "Divine Guardians" Curse: If you can get the invulnerability shield Curse, use it. It deflects projectiles. In a fight that is 90% projectiles, this turns you from the prey into the predator.
- Stay in the Bottom Third: Don't let him get behind you. Try to keep Kallamar in the top half of the arena so you have the maximum amount of time to see his projectiles coming down toward you.
- Ignore the "Greed" Hits: Hit him once, maybe twice, then move. If you try for a third hit, he will swing that sword, and you will lose a heart.
Kallamar is a test of patience. The game spent two biomes teaching you to be fast and aggressive. Now, it’s teaching you to be careful. Listen to what the game is telling you, or prepare to spend a lot of time seeing the "Death" screen in the murky depths of Anchordeep.
