Crusader:
Eastern Plaguelands
Scarlet Archmage (50 - 57)+ 0.01% (71,634)
Western Plaguelands
Scarlet Spellbinder (52 - 58) 0.18% (430,103)
The Crusader Enchant is worth 200g, Though A Very Low Drop Rate, Best Off Buying it Unless your Lucky
LifeSteal:
Scholomance (Dungeon)
Spectral Researcher (53 - 60)+ 0.84% (25,940)
The Lifesteal Enchant Is Low Aswell, worth just over 400g, Its Not worth Buying, But not worth farming for either, I just recommend Doing Scholomance Normally, and if you get it your lucky, if you don't too bad =D
