Update: Passive changed, though still has similar mechanics to the old one.

Why this Passive: As the description says, the passive is a guaranteed revive, similar to Guardian Angel but with lesser health. Burning Grave protects Zaphira from any nearby threat, by dealing damage and driving away champions waiting for her revival.
