FastTools is a Valheim mod that reduces the usage delay of the build hammer and other placement tools, with fully configurable delay and stamina cost. Run the game once with the mod enabled to generate the config file and fine‑tune your settings.
FastTools is primarily client-side but can also be installed on a server to sync configs and optionally enforce settings via ConditionalConfigSync. Requires BepInExPack Valheim or any compatible mod manager 🙂.
