 Using the grapnel on the ledge beside the squid monolith, followed by
 casting the Trigger spell on the monolith, crashes the game.

 * A new character only acquires the Trigger spell by starting as a mage.
 * The grapnel item (from the Adventurers' Guild) is not naturally
 available to mages.
 * This bug is possible for a non-mage imported character who learned the
 Trigger spell in a previous game.

 The original interpreter also does this.
