Polarities Mod/Bisector

The Bisector is a Hardmode enemy that spawns underground in the. While ordinarily acting like a regular worm enemy, if it aligns itself with the player in any of the four cardinal directions it will suddenly charge at them in a straight line, unaffected by gravity until it emerges from the tiles closest to them. In Expert Mode, when below half of its maximum health it will gain the ability to charge diagonally as well, for eight directions in total.
