Hardiness

Blocking 
An instantaneous version of the Armor spell – adds to the Damage Resistance of the subject for one attack. This spell is not cumulative with Armor – only the stronger spell applies. Remember that only one Blocking spell may be cast in a turn. A mage cannot follow up a failed Iron Arm with a Hardiness spell, for instance.

Cost: 1 per point of DR (maximum of 5). 
Prerequisite: Block.
