Draconic Reservoir

Absorb 6 pts of energy dam/lv (max 60). Each
round, as a swift action, you can release 1d6
points of this energy into any melee attack. The
first creature struck with this attack takes the
energy damage in addition to any other
consequences of the attack. The max amount of
energy the spell can absorb remains fixed and
does not change with release. Draconic Reservoir
does not stack with protection from energy.
