Lifeblood is an instant cast haste buff and minor heal available to sufficiently skilled herbalists. It is a free, instant heal that increases in power for every 75 skill points in herbalism. It does not scale with spell power, although it is affected by certain talents, and receives bonus healing equal to roughly 1.5% or 1.6% of the caster's maximum health. The heal can crit. The scaling is nearly insignificant. Lifeblood also now improves haste rating.
