sanctuary not adding +% to undead

[WarBlade]

i've tried +720% damage vs undead at level 20, it makes zero difference in damage.

1.) What Combat Skill are you using? :huh:
2.) How are you expecting Sanctuary damage to occur?
3.) What are you attacking?
4.) What are you looking at to determine that the skill does no extra damage to Undead?

If you are using Charge and Zeal, you should be seeing a difference to damage output versus Undead when you hit them. Also you mention Cleansing when the entry itself mentions Cleansing amplifies the Magic Damage. AFAIK that won't add to the 720% Physical Damage number you supplied.
