ForestGammeltroll

v1.0.0·Updated 2026-10-12

A rare, moss-covered Gammeltroll now roams the Black Forest. It replaces some open-world Troll spawns and turns to stone on death, leaving rock you can mine for copper.

About this mod Author’s original text

Forest Gammeltroll

Something old has taken root in the Black Forest.

Forest Gammeltroll adds a rare, moss-covered cousin of the Deep North's Gammeltroll to the Black Forest. Instead of snow and frost, it carries the forest on its back: mossy stone skin, a hanging beard of lichen, and green firs growing from its shoulders. When it falls, it turns to stone, and the petrified remains are laced with copper.

Features

  • A new Black Forest mini-boss. Whenever a regular Troll spawns in the open Black Forest, there's a chance (25% by default) it's a Forest Gammeltroll instead.
  • Only open-world spawns are affected. Troll caves and raids are left untouched.
  • In multiplayer, the roll happens once on the machine that owns the area, so you'll never get duplicates.
  • Tougher than a Troll, gentler than its northern kin. 1500 health and roughly 2–2.75× a Troll's damage. It keeps the Gammeltroll's huge reach, ground slams and throw attack, so keep your distance and your stamina.
  • A Black Forest look. Snow becomes moss, the frosty beard becomes lichen, and the snowy firs on its back become green. Every texture is generated in-game from Valheim's own art, so the download stays tiny.
  • Turns to stone on death. Like the Gammeltroll, it petrifies into a statue. Break it, then mine the rock for Stone and Copper Ore. Any pickaxe works, from the Antler Pickaxe up.
  • Stars without the paint job. Starred Forest Gammeltrolls keep their natural colours, including with Star Level System installed.
  • Fully configurable. Spawn chance, health, damage, size, AI ranges and copper yield can all be changed live with ConfigurationManager, with no restart needed.

Configuration

Settings live in BepInEx/config/com.voxxsidus.forestgammeltroll.cfg and can be edited in-game with ConfigurationManager. Gameplay settings are server-synced: on a dedicated server, the server's values apply to everyone.

| Section | Setting | Default | Description |

|---|---|---|---|

| Spawning | SpawnChance | 25 | Percent chance an open-world Black Forest Troll becomes a Forest Gammeltroll |

| Spawning | AllowStars | true | Whether it can spawn with stars, using the Troll's normal level-up chances |

| Stats | Health | 1500 | Base health (Troll: 600, Gammeltroll: 3000) |

| Stats | DamageMultiplier | 0.75 | Multiplier on the Gammeltroll's damage, applied to every hit |

| Stats | ModelScale | 1.0 | Size relative to the Gammeltroll (1.0 ≈ 4× a Troll) |

| AI | ViewRange | 50 | How far it can see you (Troll: 30, Gammeltroll: 300) |

| AI | AlertRange | 30 | Radius in which it notices you |

| AI | MaxChaseDistance | 200 | How far from home it will chase you |

| Petrify | CopperOreWeight | 0.5 | Copper Ore vs Stone ratio when mining the remains (0.5 ≈ one third copper) |

| Visual | MossTint | green | Colour of the moss (client-side) |

| Visual | SnowToMossThreshold | 0.48 | How much of the old snow becomes moss; lower means more moss (client-side) |

How often will I see one?

At the default 25%, each new patch of Black Forest you explore has about a 1 in 84 chance of producing one. In practice that's roughly one per hour of exploring new forest, and much rarer while you stay in areas you've already explored. Raise or lower SpawnChance to taste.

Compatibility

  • Everyone must have the mod. Clients and server need it installed, with matching versions.
  • Star Level System: supported. Starred Forest Gammeltrolls keep their normal colours automatically.

Installation

Install with a mod manager (r2modman, Gale, Mod Manager), or manually:

  • Install BepInExPack Valheim and Jötunn.
  • Copy ForestGammeltroll.dll into BepInEx/plugins/ForestGammeltroll.

For server admins

With devcommands enabled, fgt_testspawn [count] pushes regular Troll spawns through the open-world spawn path in front of you, so you can check spawn settings without waiting. Stand in the Black Forest when you use it.

Changelog

1.0.0

  • Initial release.

Install & use Install: BepInEx plugin

  1. The archive from playbuff is the mod itself — usually a BepInEx plugin (a .dll or a plugin folder once unzipped).
  2. Recommended: use a community mod manager (such as r2modman) — pick this game, import the mod, and the manager sets up BepInEx and its dependencies for you.
  3. Manual route: install the BepInEx loader in the game folder, then drop the unzipped .dll or plugin folder into BepInEx/plugins/.
  4. Launch the game — the BepInEx console logs every plugin it loads; seeing this mod in the log means it is installed.

Mods with listed dependencies need those installed too, or they will not load. Options are usually changed in-game or in the plugin's config file. In multiplayer, the host and every client need the same mods installed.

Dependencies

Install these first, or the mod will not work:
