Working for the scientists of Telaria, Mildred was seen to have an eye for amazing Cadavers to work upon experiementing to make the perfect Undead soldiers. She quickly got a new nickname… The Corpse Collector.
Corpse Collector is a Force affinity epic from the Undead Hordes. Corpse Collector is an underrated epic with a group of strong abilities including a leech, AOE decrease accuracy, and a multi poison A3. These skills combined are great for Clan Boss, Iron Twins and for Dragon. Although not top tier, Corpse Collector is strong and worthy of your time.
There are better poisoners, better leech champions but the variety of the kit on Corpse Collector and the possibility of different boss fights she can support make her mid-tier.
Make sure you build with accuracy to land those debuffs!
