This overhauls segmented enemies such as worms by making it so when a segment is damaged, the entire enemy becomes immune rather than only the segment itself. This pretty much buffs them overall. Can't cheese the Destroyer of Worlds anymore with piercing weapons.
This does not affect the Eater of Worlds as each segment has it's own health pool.
If you encounter any errors with some modded NPCs, or it simply doesn't work with them, please complain to that mod's authors to make their worms use the better system shown in ExampleMod's ExampleWorm.
