This spell provides its target with limited immunity to weapon attacks. The spell will last ten minutes or until the target breaks the spell 19s physical requirements. The target of the spell must plant his or her feet and raise both arms above the head without crossing them. Moving either foot or lowering an arm ends the spell. Any body damage taken also breaks the Fortress. The target may touch-cast spells (on themselves only) but may use no other Game Abilities without breaking the protections of the Fortress. While the Fortress lasts, the target is immune to weapon blows of 10 or less.
