Venomancer's attacks slow enemies and deal damage over time.

Infects an enemy with a plague that does damage on application then slows the target and deals damage over time based on their maximum health. When the debuff ends for any reason, all debuffs from Venomancer on the initial target and the plague are spread to nearby targets. Additional spreads beyond the first do not deal impact damage.
