Ferena Drake is a terrifying enemy thanks to her Shiver, which not only severely slows the enemy's offensive, it protects her as well in combination with her Icy Blast. Shiver completely shuts down creatures with movement or range debuffs.
On Awakening, Ferena Drake gains a sizable health increase and Accursed, which makes her powerful in offensive operations as well.
*NOTE: Fields that contain the text *See above means the effect remains the same until said otherwise.
Ferena Drake can be acquired through pvp post-season rewards for the champion and semi-/quarter-finalists. Her first appearance as a pvp reward was during the February 2014 pvp season.
