Benefit: You may expend a turn attempt to make a glorious stand against your enemies. For a short duration of time, you gain DR 20/epic, take reduced damage from elemental and negative energy, receive double healing from positive energy, and are immune to secondary effects of attacks such as 'wounding' or 'vorpal'. Each time you take damage, you gain the effects of a Cure Light Wounds spell.
This is the best I was able to find looking it up, anyone have more detailed info? Does it slow movement? How long does it last? How long is the cooldown timer? Is the CLW affected by the double healing effect or your own healing amp gear/enhancements?
