Must be cast at a specially constructed stone tower, at least 10 yards high, in an open, cloudless area. A sacrifice is offered and the ritual called out.

For each such spell, the caster must sacrifice 5 POW. The chance of successfully contacting the deity is equal to half the caster’s (reduced) POW. If the roll succeeds, the deity or some aspect of it will contact the caster in a semi-friendly manner after a few game hours or days. The deity is unlikely to give non-worshipers anything of value. If the deity is bored or offended the god will likely squash the caster, or
drive him or her insane, and so get some inhuman pleasure from the situation
