Better Wither Skull Rates

Summary

I know, I know. You're probably saying "Oh look... Another Wither Skull DataPack/Mod".

Well unlike most that just make the drop chance 100% or super high. Mine increases it in a way more balanced than usual.

The rates are increased but not rediculous.

Info

Drop Rates Per Looting Level: - No Looting = 5% - Level 1 = 10% - Level 2 = 15% - Level 3 = 20%
