[Magic] Resurrection

[cbower]

To start with, any mage in the group who knows the spell at 15+ can contribute as much energy as he wants, which will include 1 powerstone for each. The limit of 3 only applies to mages who know the spell but not at 15, and they don't count towards the spectator limit of 100, either. So it can be done, but it's not easy so the spell should cost a ton per casting.

A Charged Scroll, a la Dungeon Fantasy, would do the trick nicely, too.
