Mob Effigy

Mob effigy are going to be statues of mobs and are also going to be the same type of entity as armor stands.

Mob effigy will produce status effects corresponding to the mob effigy's type in a 45x45 area.

The mob effigy should probably be obtainable as a super rare mob drop or as chest loot from any structure.

I will show some examples here.

Creeper-Player gets inflicted with slowness VI but also gets inflicted with night vision I.

Drowned-Player gets inflicted with blindness but gains unlimited water breathing.

Shulker-If the player is damaged by any mob they will get inflicted with levitation for 10 seconds but they will get resistance I
