• Added reasons for unable to foxify, (either Foxtype or admin setting)
• Revamped code logic, theoratically more rigid

Passive Skill [Foxiality]

• No longer trying to tame foxes with NoAI
• Removed fox kill penalties

Passive Skill [Timidity]

• Fixed Fear bossbar not being removed if you change origin while it is visible
• Added a hint about using [Sneak] to highlight nearby fear source, when first time getting Fear effect

Other

Added support for Origins-Legacy, tested with latest version on 26.3 Origins-Legacy-1.12.20+26.3.jar.

Note: This version is seldomly tested. Most discrepancies happens with Vanilla Minecraft's own change, and lack of Pehkui in higher version.

The same version might be usable in other versions where Origins-legacy is being used. You can install it as datapack + resource pack to try it out.
