So fiddled with the new Pally enhancement "Divine Sacrifice". I like it and I think at high levels it'll be pretty handy with no limit to it's use and only a 3 sec cool down. At high levels the HP and SP cost are not all that big a deal. However I do have one thing I wouldn't mind seeing changed. Pretty unimportant I am sure but would help to make it more clear I think. Here is the description:

Paladin Divine Sacrifice I:
Prereqs: Paladin level 5, Paladin Extra Smiting II, 15 Action Points spent
Cost: 1 Action Point
Benefit: Giving up some of your life force to win the battle, you empower your next blow against your foe. This attack deals an additional 5d6 Good damage to evil opponents and increases the critical multiplier of your weapon by 1, but costs you 10 hp and 1 sp, whether or not the attack is successful. (3 second cool down)

While I know some people will just say "Oh get over it it's no big deal" I think to be more clear it should state Holy Damage not Good Damage. Good Damage makes me think it's more like Pure Good when it isn't. It doesn't work on anything that isn't evil like Pure Good does. Certainly makes it more clear to newer players. just a thought.
