I just recently turned an account into a tank (had a great start with 99 range 99 mage).
-75 atk (SoL)
-Keep str low to thwart turmoil (Mine is 61)
-70/75 Def (Im saving up for a divine so I'm going for 75)
-99 Hp
-74/77 Pray (I'm going for 77 for Augury, but for edge purposes 74 for Rigour)
-99 Range (Duh?)
-94/99 (94 if edge 99 if hybrid)
Puts my tank at lvl 101 (Perfect for downing turm pures and zerkers)
[Edit] Also don't waste your time getting a chaotic x-bow, the wait to get rigour/augury is enough. + theres alot better stuff you want to slot than a little more range bonus, because with 99 range +Rigour your GOING to hit, and its going to be hard. Add in a Divine and your the biggest asshole walking around edgeville.
