Concordant Opposition

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 ~20-30SP

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).

Developer words on the topic
With a prototype system, we're likely to err on the side of caution at times, especially when it's related to something we normally don't do (like SP healing). We'll be tracking all the information we receive from it, and are very likely to make adjustments to things we find too weak or excessively powerful.}}

 * developer = |developer = : Guard effects should not stack with themselves, so it would be classified as a bug that is potentially subject to change.}}
