Venomancer

Launches a ball of venom in a line, poisoning enemy units so that they take both initial damage and damage over time, as well as suffering slowed movement. Venomous Gale deals damage every 3 seconds over its duration.

Adds poison damage to Venomancer's normal attacks and slowing movement speed.

Summons a plague ward to attack enemy units and structures. The ward is immune to magic. Wards gain the Poison Sting level from Venomancer, dealing 50% of the full damage.

Venomancer's attacks deal extra damage based on how many debuffs the attack target has. Extra damage is dealt as magical damage. Only counts debuffs from Venomancer or his Plague Wards.

Infects an enemy with a deadly plague that does an initial burst of damage and additional damage over time based on the unit's maximum health. The plague slows the target and nearby enemies based on their distance to the target. When the target dies or the debuff expires, all nearby enemies are infected with a noncommunicable version of the plague.
