Heals the target for X over 7 sec. When Lifebloom completes its duration or is dispelled, the target instantly heals themself for Y and the Druid regains half the cost of the spell. This effect can stack up to 3 times on the same target.
Lifebloom is a druidheal 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 and refund mana equal to half the mana it cost to cast the spell.
Lifebloom costs 978 mana before reductions at level 80.
Each time that Lifebloom is cast on a target, the Lifebloom stack is incremented by 1 up to a maximum stack of 3. The entire stack shares a single expiration timer, which is refreshed to max duration every time Lifebloom is recast on the target. Therefore, a single casting of Lifebloom is sufficient to maintain an entire 3-stack.
Each Lifebloom in a stack will bloom if the stack blooms, so if a 3-stack expires the direct heal will be three times that of a single Lifebloom, and the mana returned will likewise be for the whole stack.
The heal over time portion for this spell ticks every second, unlike most other HoTs which only tick every three seconds.
The HoT is enhanced by 6.53% of your spell power per stack per tick. The bloom is enhanced by 38.57% of your spell power.
[Empowered Rejuvenation] increases the benefit the spell gains from spell power by 20%. Note that this is a 20% increase to the amount gained; it does not mean that Lifebloom gains an additional 20% of your spell power.
[Genesis] increases the amount of healing done by 5%.
[Natural Perfection] increases the critical effect chance of the bloom heal by 3%.
[Nature's Splendor] increases the duration by 2 seconds, adding two additional ticks at full strength.
Subtlety reduces the threat caused by the spell by 30% and reduces the chance that it will be dispelled by 30%.
Tree of Life reduces the mana cost by 20%. This applies both in and out of Tree of Life Form. The mana returned on bloom is not affected by this reduction.
Casting Lifebloom on a new target grants that target as many applications as the old target had. This effect will not occur while in Tree of Life Form, or when Lifebloom has less than 2 sec remaining.
When tank healing, apply Lifebloom one stack at a time. When the spell is about to end, let it bloom if the tank needs the extra healing, otherwise refresh it before the final tick and repeat the process.
Stacking and maintaining 3 Lifeblooms on a target provides a reasonable amount of healing every second, though it is not very mana efficient as you will never get the mana return from the bloom.
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.
Patch changes
Patch 3.2.0 (2009-08-04): The final heal that occurs when this spell blooms has been reduced by 20% on the base and on the spell power coefficient.
Template:Patched
Patch 3.1.0 (2009-04-14): Mana cost of all ranks doubled. When Lifebloom blooms or is dispelled, it now refunds half the base mana cost of the spell per application of Lifebloom, and the heal effect is multiplied by the number of applications.
Patch 2.4.0 (2008-03-25): The spell coefficient on the bloom is reduced by 20% (from approx 42% to approx 34%). The talent [Empowered Rejuvenation] now applies to the bloom.
Patch 2.3.2 (2008-01-08): The healing bonus is no longer based on the first cast but will take on the strength of the incoming Lifebloom casts.
Patch 2.1.0 (2007-05-22): Each additional application of this spell will now include the full bonus from effects which increase healing. The final heal, however, is still unaffected by stacking multiple applications of this spell.
