Pretty much a test mod for me to learn Fabric, will possibly update it but for now it

Enchants

Execution, an alternative to Sharpness, instakills below a certain % threshold

Hollow core, a Mace enchant, which makes it do uh. Mace things. Horisontaly, based on your velocity

Arbalest, a Bow enchantment, an alternative to Power, shoots a much stronger and heavier projectile upon fully charging

Enemies

Vitrified, a Desert skeleton stays partially invisible until it attacks something. Circles around the target and appears in groups. Also, is the way to get arbalest
