A War Party of Magi

A group of magi acting together can use Wizard's Communion (see ArM5, page 160) to cast high magnitude Intangible Tunnel-style effects with high Penetrations. The Wizard's Communion can also be used to cast effects through the tunnel.

For example, 4 magi who each know Wizard's Communion of at least level 10 work together to cast a level 20 Intangible Tunnel-style effect. Only one of the magi needs to actually know the Intangible Tunnel-style effect. When that magus casts the Intangible Tunnel-style effect the Penetration is calculated as if the effect was only level 5.

Using Wizard's Communion combined with Intangible Tunnel-style effects is a good strategy for members of the Tribunal to take when trying to eliminate a magus who has been Marched. Groups of magi can also work together in this way to prosecute a Wizard's War, although to be strictly legal, all the magi involved in the Wizard's Communion must declare Wizard's War on the victim.
