Polarities Mod/Convective Wanderer

Convective Wanderers are a Hardmode enemy that appear in The Underworld after Golem has been defeated. Unlike most worm-type enemies, rather than charging the player directly, they will attempt to encircle them, pulling the circle tighter as their health is lowered. Additionally, they will only target players that are submerged in lava, wandering aimlessly otherwise. Convective Wanderers inflict on hit, briefly but rapidly sapping players' life. They can spawn with a variable amount of segments, their maximum life depending on how many they have.
