Concordant Opposition

Concordant Opposition is a guard effect available on Green Steel items.

This item is imbued with the energy of concordant opposition. Those who rest at the pinnacle of supreme balance can do nothing but gain. When the wearer of this item is successfully attacked in melee, there is a chance that the item will bestow temporary hit points and grant spell points to the wearer.
 * a 4% chance to gain a temporary 30 hit points, and a separate roll for a 4% chance to gain ~20-30 spell points.

Stacking
Currently one weapon and one accessory will stack, while multiple accessories or multiple weapons themselves do not stack. This is probably not working as intended and might get changed in the future (see developer posts below).
