User blog comment:Emptylord/Custom Champion - Yaga the Stray Little Witch/@comment-72.13.214.193-20120906061150

Yaga uses a secondary resource system, in addition to mana. This works similar to  Renekton 's Fury and  Rengar  's Ferocity, empowering her abilities automatically when "Blunder" is ready. (SO is it like Chi in world of warcraft Monk class?)
