This spell does one of two things. If you are at the square of a temple of your god, the spell will magically add to the seal of the door. This makes the temple tougher to be entered by thieves and Followers of rival gods. When at the square of another god's temple, it lowers the magical seal on the door - perhaps enough to allow you to enter using an
LV order. When at the square having a temple, issue the CAST SPELL order: C 34 (Spell Pts). It takes 6 Action Pts. The more Spell Pts allocated, the better.
