Well the colosuus does much more dmg but its the set bonuses I am after. This is my plan tell me whatca think, I am going to equip the Disciple set and the Bul Kathos set to get the following total stats from the combined sets:

+ 4 to All Skills
+ 200 to Attack Rating
+ 200% DMG to Demons
+ 200% DMG to Undead
+ 175 to Defense
+ 10 Strength
+ 20 Fire Dmg
+ 100 to Mana
+ 50 to all resists

And some Poison Dmg

Good PVM but lousy pvp, and only 3 empty slots for leeching. I am thinking with a nice arreats and some good rings this setup will kick ass!!!!

Doofus
