World of Warcraft®

Anytime a damaging attack brings you below 30% health, you gain an absorption shield equal to 20% of your total health lasting for 20 sec.

This effect cannot occur more than once every 90 sec.

Discipline:
When you cast Penance, there is a 40% chance your next Power Word: Shield will both ignore and not cause the Weakened Soul effect.

Holy:
When you cast Greater Heal or Prayer of Healing, there is a 40% chance your next Prayer of Mending will not trigger its cooldown, and will jump to each target instantly.

Shadow:
Periodic damage from your Shadow Word: Pain has a 5% chance to reset the cooldown on Mind Blast and cause your next Mind Blast within 12 sec to be instant cast and cost no mana.
