Shadow slip no longer has high priority in casting. It should go back to high priority because sometimes you get a red area when casting a power and is impossible to avoid.
Arms of hardar is useless, 40 magnitude damage is too low. I do more damage using at wills
Infernal spheres is also useless. It should have a reflect like on mod 15, or be like barkshield enchantment absorbing a fixed ammount of damage per sphere
Creeping death damage is too low and it doesn't stack like it was on mod 15. I chose executioner gift on that without any thinking
Prince of hell is not good. It could be useful if it gives hit points instead of armor penetration
Dark revelry buff is not tempting. A damage or damage resistance buff to the party would be nice
