SpecialAttack
⚠️ WARNING: This mod is still in testing. Do not use it yet.
📌 This mod was inspired by and references sighsorry's SecondaryAttacks.
Adds unique special attacks to each weapon category in Valheim.
Every weapon type gets a distinct skill with cooldown tracking, configurable damage multipliers, visual/audio feedback, and an optional custom activation key.

How It Works
- Secondary attack key triggers specials by default — each has its own cooldown
- Optionally bind a custom key (
SpecialAttackKey) to separate specials from vanilla secondary attacks
- Custom key pressed → special attack only (no secondary swing)
- Custom key pressed while on cooldown → nothing happens
- Secondary attack key → always vanilla secondary attack
- Cooldown icons appear on your HUD
- Charge bars shown on screen for Sneak Ambush and Charge Slash
- All values are fully configurable via the BepInEx config file
