Mutant Skeleton Armor Tweaks
Mutant Skeleton Armor Tweaks (MSAT) is an add-on that aims to customize and balance the effects from the Mutant Skeleton armor set from Fuzs' Mutant Monsters mod.
Features
In game config
- Toggle each armor piece's default effect in the in game config (or the config file).
- Config is synced from servers to clients upon joining.
- Only OPed players can modify the mod's settings in game. Singleplayer worlds are not affected by this.
Crossbow compatibility
- A config toggle allows the Mutant Skeleton Chestplate to buff crossbow draw speed. (Also buffs other weapons with the #c:ranged_weapons tag)
Custom tooltips
- Only available when Custom Tooltip API is installed.
- Effect descriptions are dynamically displayed (when the effects are active in the config) inside each armor piece's tooltip.
- These descriptions are shown as a potion effect (legs, boots) or a line displayed when the player presses the corresponding keybind (
Shiftby default).
Compatibility
- Eldritch End: Mutant Skeleton Skull compatible with Eldritch End's infusions.

## 3.0.0+1.20.1
### Features
### Fixes
## 3.0.0+1.20.1
### Features
- Added YACL dependency
- This implementation allows players to change the config from the game, in the Mods menu
- The config can successfully be changed freely in:
- Singleplayer
- Servers, only if the player is OP
- Added S-Lib dependency (2.1.0)
- Changed tooltip lines to be registered with Custom Tooltip API, adding it as a soft dependency
### Fixes
- Fixed config not syncing with the server's, allowing players to set a different config than the server's and using that to exploit disabled effects by enabling them client side
- Restored the Eldritch End compat from 2.1.0, due to a newer version of that mod not releasing

Added a new implementation to handle infusions on the Mutant Skeleton Skull (waiting on Eldritch End's update)
#### THIS ONLY WORKS ON NEW ITEMS!!!
- No longer copies over the entire NBT stack to the infused item
- Instead, adds a tag that describes the infusion type and material
- Then, Eldritch End handles the tag and gives it the correct infusion stats

# v2.1.0
### Mutant Skeleton Skull is now compatible with Eldritch End's infusions (Thank you [ImEden6](https://modrinth.com/user/ImEden6) for the feature!)
### Mutant Skeleton Skull is now compatible with Eldritch End's infusions (Thank you [ImEden6](https://modrinth.com/user/ImEden6) for the feature!)
- Fixed the logic in SmithingMenu to ensure the Mutant Skeleton Skull correctly identifies as a HEAD slot item during infusions, preserving all NBT data and Tierify attributes.
- Modular Mixins: Moved compatibility logic to an optional, isolated mixin configuration (required: false) with a dedicated plugin check. This prevents the mod from crashing if Eldritch End is missing or if classloading loops occurs.
- Added #prominent:limit_8 tag to the entire Mutant Skeleton set

- The mutant skeleton skull is now enchantable with helmet enchants!
- When placed and broken, the skull keeps its NBT data, meaning all attributes are conserved
