Note that the caster loses health right before the target is resurrected (not at the start of the cast). If caster has 240 health before casting, both the caster and the target will have 120 health afterwards. If the spell is interrupted, the caster will not have lost half of his health.
Combine with Vital Weapon or Generous Was Tsungrai to resurrect allies with increased health. Generous was Tsungrai has the added benefit of healing you right after the resurrect.
The health loss can make this an awkward skill for PvP. However the low cast time means that it is one of the more dependable means of resurrection outside Resurrection Signet.
Aside from signets, this is the cheapest resurrection skill in the game.
If within earshot of a spirit, use Ghostmirror Light to heal yourself and the target after resurrecting.
