Crawl Custom Bosses
Six new final bosses for Crawl. Each has its own pixel art and animations, its own sounds, its own arena, and stations that the three ghosts run against the hero. Each boss's health bar sits at the top of the arena, like the vanilla bosses' bars.
| Boss | The fight |
|---|---|
| Asterion | A giant minotaur in a stone labyrinth. Bait his charge into a wall to stun him. Each phase brings three new groups of traps, and one ghost fires a whole group at once. Ghosts also slam the gates and can ride the Horn on his head to steer him. |
| Ignis, the Hoard Wyrm | His fire dies on his gold mounds. Overheat a mound until it melts, and his greed drags him off to wallow in it. That is your window. |
| The Drowned God | You can only hurt it while you are mad enough to see its face. Too mad, and you start seeing false faces. Ghosts whisper you madder, flood your path and plant lies. |
| Hafgufa, the Kraken | It heels the ship so everything slides to the low rail. Knock out the glowing pin to drown a rail, and its head surfaces there. |
| Magister Vael | He casts from a warded circle. Knock him out through the gap in the ward to break his spell. |
| Grukk, the Goblin King | Light the fuse on his throne-cart. If his court cannot douse it, the blast throws him off right next to you. |
Install
Use r2modman or the Thunderstore Mod Manager and pick the Crawl game. The manager installs the BepInEx pack for Crawl. To install by hand, put the files from plugins into BepInEx/plugins/CrawlCustomBosses/.
Settings
Every boss has its own config file in BepInEx/config:
| Boss | Config file |
|---|---|
| Asterion | com.zac.labyrinthboss.cfg |
| Ignis | com.zac.boss.dragon.cfg |
| The Drowned God | com.zac.boss.cthulhu.cfg |
| Hafgufa | com.zac.boss.kraken.cfg |
| Magister Vael | com.zac.boss.wizard.cfg |
| Grukk | com.zac.boss.goblinking.cfg |
The files are created the first time you launch the game. Each one has these settings:
Mode- Rotation (default): the boss joins the normal pick of final bosses.
- Always: every run ends with this boss. If more than one boss is set to Always, the game picks one of them at random.
- Off: the boss never appears.
Weight: how likely the boss is to be picked in Rotation, compared with one vanilla boss.Enabled: switches the boss on or off.
Notes
- Bot ghosts use every station except the seats meant for human ghosts.
- The boss music is the game's own.
- Report problems with a copy of
BepInEx/LogOutput.log.
