This spell opens up the portal between the natural world and a daemonic world, allowing uncontrolled Daemon hordes to pass unhindered. The portal appears anywhere within 48 yards of the caster. The caster cannot control the Daemons that appear. They behave either in a random manner (consult the Successive Summonings Table) or according to the gamesmaster's desire. Daemons summoned in this way often charge and attack the nearest non-daemonic creatures as soon as they get the opportunity.
6D6 Lesser Daemon and one Greater Daemon are unleashed upon the world at the start of every game turn. The Daemons are not allied to the caster and will not spare the caster from the slaughter.
The Daemonic Portal remains open for 10D6 game turns. As the portal closes, any remaining Daemons become unstable and disappear.
