a shaman spell that takes willingly given hps from group members and transfers it to the caster. A bit like energy drain but unlike edrain, it is not an evil spell. Castable only on group members and mob members hav a chance to save vs spell. If mob member saves he will become aggro to caster. A successful transfer wellness will give caster 150hp at the cost of 75mana to cast.

Instead of hitpoints, it could return mana to the shaman. The cost could either be in group memeber mana or in group memeber hitpoints, and the return could be a possible 2/3's return from the group total. A max or min could be stated so that there aren't any 700 mana returns(instances of a large group). I would also recommend against the use of it on mobile followers.
