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.

Summons an Air Totem with 5 health at the feet of the caster for 6 sec, granting raid members within 40 yards immunity to movement-impairing effects.

When a totem is replaced or destroyed before its duration expires naturally, its cooldown is reduced in proportion to the lost duration, up to a maximum of 50% of the full cooldown.

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 on a target located within your Healing Rain, allies within the Healing Rain share healing equal to 20% of the initial healing done.

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