Wither Tweaks
Control whether wither has invulnerability or can destroy blocks
About this Mod
Overview
Designed to be used to farm Withers easily in tech modpacks, the mod allows you to modify (through config) 2 things about the Wither:
-initial invulnerability and explosion, default to false, having it to false makes Wither spawn instantly without charging time and explosion
-which blocks can break, default to 1, this config option is defined in range [0,2] and this is how it works:
0: Wither can't break any block
1: Wither can break most blocks but not tough blocks like obsidian
2: Wither can break all blocks it usually breaks, basically default Wither behaviour
Even if the 2nd is set to 0, it won't prevent the Wither from breaking blocks with the initial explosion. If you want the Wither to not be able to destroy anything make sure to have the 1st on false and the 2nd on 0.
