With the spell the caster can link himself with their rift entity, allowing their minion to share a portion of their pain. The spell will activate when the caster takes a large amount of damage. The combined power of the casters entities will decrease this damage threshold, and also increase the spell duration. Knowledge of the spell will allow more damage to be shared with the rift entity. The damage is distributed but not lessened (unless the riftwalker is particularly powerful), and can still kill. This spell uses 4 rift sparks.
