Overview

Vampirism registers custom loot functions (Registries.LOOT_FUNCTION_TYPE). They can be used anywhere vanilla loot functions are accepted (loot table functions, given_item_modifiers, …).

Every function object has a "function" key naming the type, and – since they all extend LootItemConditionalFunction – an optional "conditions" array of loot conditions.
