StructureDamageTweaks

v1.3.2·Updated 2026-09-22

Allows modifying damage done to structures in a very customizable way. Includes an option for regular auto-repairs.

About this mod Author’s original text

In vanilla Valheim, structures can be pretty sturdy. Mods can easily turn your fortresses or ships into houses of cards though. This mod aims to remedy this.

Structures in the game will be put into a configurable number of categories. By default, the mod just differs between ships and player build structures. Non-player structures are ignored.

Whether a structure is in a category can be determined by:

  • Name of the structure.
  • Material of the structure.
  • Exclude non-player structures.

For each category one can modify the damage done to the structures in two ways:

  • Using global keys, which are used by vanilla Valheim to determine which boss has been defeated.
  • Using any item that needs to be in the player inventory with an effect range that can also be configured.

If one of the conditions is satisfied, the damage done to structures will be reduced accordingly.

Example from the default config:

  • After defeating Yagluth, all player structures will only take 50% of the usual damage.

Furthermore, auto-repair of structures can be configured in a very similar way. Using boss keys is not possible here. This is mostly meant for automatically repairing hard to reach stuff that might have been hit by an AOE attack.

  • If carrying an item that has to be defined in the config, every 2 minutes all player structures within 100m of the player will be repaired by 5%.

Installation:

Simply unpack and put into BepInEx/plugins folder. Obviously required BepInEx

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:
