Forbiddance

Cleric 6th level spells

It takes 6 rounds to cast the spell. Forbiddance seals off 60 cubic feet per level from teleportation, planar shifitng, astral and etheral travel, and summoning. Those spells just don't work. If a creature teleporting, being summoned,etc. has the same alignment as yours, than they ignore all effects except planar shifting. If a creature with a different alignment enters normally, than they take 6d6 damage (spell resistance applies). If their alignment is different from yours both in respects of good and law, than the damage is 12d6 instead. Forbiddance cannot be dispelled by a caster of a lower level. You must use a sprinkling of holy water and rare incenses worth at least 1,500 gp, plus 1,500 gp per 60-foot cube. If a password is desired, this requires the burning of additional rare incenses worth at least 1,000 gp, plus 1,000 gp per 60-foot cube to cast the spell.
