number of spell schools for theurge

[mrbadexample]

How many spells schools would be optimal for a theurge out of curosity?

I'm currently working on a build and have 34/35 WIS at lvl 40 with epics in 3 Schools. would that be good enough for most places including Hells or should I make drop a spell school for more WIS?

mine has 3 epics and maxed wis ( 66 with arti - 54 base with great wis X ); there's just enough room for that and legendary ref/pen/evo

[mrbadexample]

so you would say epic in evo/Div and then book what ever for a 3rd?

yup. i chosed necro for eternal return and slighty better dc on some spells; this because i'm used to play with bots that give epic girdle while well geared characters aren't aegis-dependant, but those are all valid choices
