Rek'Sai Ability (LoL): Fury of the Xer'Sai

Rek'sai generates 25 Fury when she attacks or uses an ability. Attacks against minions, plants, and wards restore 20% less Fury.

While Burrowed, she consumes her Fury to restore 10-20% maximum health every 3 seconds (depending on level).

Rek'sai will not consume Fury if she is at full health. She loses 20 Fury per second after 5 seconds of not generating any.
