Umbral Enchantress

Umbral Enchantress is a Void affinity Demonspawn epic with a fierce set of abilities. Often overlooked she is one of my go-to champions in the arena to completely lock out a full enemy team and allow you to comfortably win the fight. Umbral has an A3 ability that will do an AOE provoke for 2 turns whilst making Umbral Unkillable. This is her signature move as a Void champion has no weak hits, therefore as long as you have enough accuracy this will always hit all of your enemies.
Umbrals A2 Block Buffs ability is also a fantastic way to beat the 2nd wave on Ice Golem 20 and prevent them from placing a team wide reflect damage buff. Umbral is also one of the best Demonspawn champions for Faction Wars for wave control, preventing the counter-attack buffs from activating in some of the hardest waves.

Umbral will also be a great champion for Kuldath the Magma Dragon in Doom Tower with the ability to lay a 2 turn provoke and therefore lock out the dragons main abilities to land Hex debuffs.

Overall one of the best epics in the game!
