I'm currently running with a 2x bard/mage.
120 Peace
120 Prov
120 Music
100 Magery
100 Evalint
100 Meditation
60 Focus
I get 19% HCI/SDI and 49% DI off of Inspire and +11 Stats/ 23 HP from Invigorate.
Usually I run 2 EVs, Then Meditate and then launch both spell songs. I can usually keep those up for 2-3 minutes if I'm not casting but I'll turn off Invigorate when I have to summon new EV's.
I use Swords of prosperity, but if I can keep myself out of the direct fighting I'll switch to a slayer book and the extra 19%SDI gives me a nice boost to my spells.
