Mob Loot Block

This mod allows players to craft blocks that can, Change Spawners to a Specific Mob Type, Spawn A Specific Mob, or Get Mob Loot Drops.

Using a Curse of Essence Binding (Custom Enchant found after level 10) Enchanted weapon the player can get Mob Bits with a specific mobs ‘essence’ bound to it (based on what the player killed)
Mob Bits in a 3×3 pattern craft into Mob Pieces, and similarly, Mob Pieces make Mob Chunks, and Mob Chunks make Mob Loot Blocks.
– This functions a lot like soulshards/deep mob learning, where you have to get kills to make a way to spawn a specific mob.

Currently there is a tag for entity types that you can get bits from in survival (any block you see in JEI/Creative tab can be obtained basically)

Currently there are Mob Loot Blocks for ALL Vanilla mobs, bit/piece/chunk/block recipes only exist for those on the default allowed tag list. (for now)
