Priests

[KissBlade]

You can communion them if you want the extra priest levels in battle.

How do you communion priests???

[Ironhawk]

Same way you commune mages. Communing raises ALL magic paths the mage already has, including holy. So, you just need a priest that has astral (or blood) magic as well as holy.

Hellpower will do it, as will propheting, power of the spheres (which is redundant with the crystal shield, btw), communion, and two unique boosters. Those are the ones I know.
