How to summon every boss in Valheim
Each boss is summoned by placing offerings on its altar, and each altar sits in a specific biome. This guide covers every boss in order: where to look, what to bring, and what you are up against. The overview table comes first, followed by one short section per boss.
Overview
| Boss | Biome | Offering | Health |
|---|---|---|---|

| Fader | Ashlands | 3 Bells | 25000 |

Every boss in this list is immune to chop and pickaxe damage, so axes and pickaxes will not hurt them.
