ExtendedBosses
Raid-style boss fights from vanilla parts only: HP phases, add waves, nests, lieutenants, shields, burn windows, threat - seen by every player, mod or not.ExtendedBosses
Raid-style boss fights for a group, from Eikthyr to Fader: HP phases, waves of adds, destructible nests, biome mini-bosses as lieutenants, shields that drop when the nests fall, burn windows, marks, ground hazards, resistance shifts and a threat table — built only from vanilla prefabs, animations and RPCs, so players without the mod see and feel the same fight.

Phase announcements — every player sees them, with or without the mod
- Profiles
Light(bosses with reinforcements),Raid(default) andHard, globally or per boss; any boss can be set back toVanilla. Everything switches without a rejoin. - Group scaling for 1–8 players: boss HP, adds, nests, stars and marks grow with the group; solo stays doable.
- Reward on top of the vanilla drop: coins, valuables, next-biome resources and upgraded gear for bigger groups.
- English and Russian messages; players without the mod get them in the language set
by
GuestLanguage. - The server's settings apply to every client with the mod; config edits are picked up without a restart.
Install on the host; guests do not need it. With the HostOwner mod (Bosses = true)
the host keeps owning the boss whoever hits it. On a dedicated server every player who may
own the boss needs the mod.
Early version: every boss is implemented, in-game testing is in progress — the numbers are starting values and all adjustable.
Compatibility
Tested with Valheim 1.0.16 (network version 40), BepInEx 5.4.23.5 (BepInExPack_Valheim 5.4.2351).
Who needs it
| Who | What |
|---|---|
| Host | required — the fight runs on the boss's owner; with HostOwner (Bosses = true) that is always the host |
| Dedicated server | recommended for settings and messages; every player who may own the boss also needs the mod |
| Players without the mod | see and feel the same fight, messages in the GuestLanguage language |
Known conflicts
- Other boss overhauls (HardBosses and similar) — do not run two at once.
- Mods that scale boss health or stars by player count or level (e.g. Creature Level and Loot Control) stack with this mod's group scaling; lower
02 Scalingor theirs.
