Lifebloom

Lifebloom is a druid heal over time (HoT) spell that becomes available at level 64. Unlike other HoTs, it will stack with itself up to three times. Each time the spell is cast on itself, the duration of the entire stack is refreshed. If Lifebloom completes its duration or is dispelled, it will bloom and immediately heal the target. Lifebloom can only be cast on one target at a time. If cast on another target the previous lifebloom will vanish without blooming.

Talents

 * Gift of Nature increases the healing done by 25%.
 * Revitalize gives you a 20% chance to restore 4% of your mana when lifebloom ticks. This cannot occur more than once every 12 seconds. It also causes Lifebloom to grant Replenishment when cast or refreshed.
 * Malfurion's Gift gives each tick of Lifebloom a 4% chance to make your next spell with a cast time free.
 * Empowered Touch makes Nourish and Healing Touch refresh the duration of a lifebloom stack on that target.
 * Gift of the Earthmother increases the bloom healing by 15%.
 * Tree of Life Form allows lifebloom to be cast on multiple targets while in tree form.
 * Genesis increases the periodic healing by 6%.
 * Nature's Majesty increases the critical strike chance by 4%.
 * Moonglow reduces the mana cost by 9%.

Tips and Tactics

 * When tank healing, apply Lifebloom to 3 stacks and then cast Nourish or Healing Touch. The direct heals will keep the lifebloom stack refreshed.
 * In PvP: players that can dispel Magic-type buffs will have to decide whether to leave the Lifebloom buff on (they continue to receive healing, then they'll get a chunk of health back), or to dispel it (in which case the target will get the final healing effect right away and can recast Lifebloom). One of the best mind-games a Druid can play in PvP.
