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
