World of Warcraft®

Whenever a damaging attack brings you below 30% health, your maximum health is increased by 25% for 10 sec, and your threat level towards the attacker is reduced. This effect cannot occur more often than once every 30 sec.

Your Frost Shock now also roots the target in ice for 5 sec.

When activated, immediately finishes the cooldown on all totems with a base cooldown shorter than 3 minutes.

Your next Nature spell with a base casting time less than 10 sec. becomes an instant cast spell.

Passive:
Increases spell haste by 5% and melee haste by 10%.

When you cast Healing Wave, Greater Healing Wave, or Healing Surge, allies within your Healing Rain share healing equal to 30% of the initial healing done.

If your Lightning Bolt, Chain Lightning, Earth Shock, or Stormstrike damages an enemy, allies within your Healing Rain share healing equal to 50% of the initial damage done.
