Rune Mechanics:
Acquisition:
Runes have a low chance of being acquired by slaying specific mobs in the world associated with their aspect. Drop rates and mobs are data driven, so these values can be changed, but defaults are as follows.
Base drop rate: 10%
Inferum -> Blaze
Glacius -> Polar Bear
Terra -> Husk
Tempestas -> Breeze
Aracani -> Enderman
Umbre -> Phantom
Infusion:
Runes are almost like enchantments, though their only application is to armor. To infuse a rune into a piece of armor, simply add the rune in an anvil just as you would a normal enchanting book. All infusions cost 30 levels and persist through upgrades (Diamond to Netherite smithing recipe). Any armor is valid, even modded armor.
