Barrier

Schools:	Abjuration

Create a magical wall or barrier. If assigned a damage type, the barrier is resistant to the type of damage selected, taking only half damage from it. The barrier's hardness and hitpoints are both equal to Arcane Penetration + Willpower paid.
Lesser Barrier
Half the cost of Barrier. The barrier is permeable (Schools) and cannot have a specified damage type. Creatures can become incorporeal or shrink in size to pass through the barrier as though it were a cage and the barrier does not stop the progress of fire, noxious gas or flowing water. Ranged attacks can be made through the barrier.
Greater Barrier
Double the cost of Barrier. The barrier does damage to anyone attempting to attack equal to the amount of damage done to the barrier. When reflecting damage this way, the barrier is also replenished by damage of the chosen type. The barrier is water-tight and a solid mass through which projectiles, fire, noxious gas or water may not pass.
