Got a level 12 eldritch disciple getting ready to come out the gate after the death of my rogue. I need help on the spell selection. It's a Warlock 5/Ur-Priest 2/Eldritch Disciple 5 (GM okayed the Ur-Priest), so I'm trying to figure out spell and invocation selection. Group has an assassin and a leadership Bard with another cleric and a knight to travel with him. We're drawing largely out of the Completes here, so please don't go outside them for things like Nightsticks.
Stats: Human, Lawful Evil
Str: 8
Dex: 10
Con: 14
Int: 13
Wis: 26
Cha: 20
Items: Artificier Monocle, Cloak of Cha +4, Periapt of Wis +6, Vest of Resistance +3. I haven't selected armor, weapon or any wondrous items outside Heward's Fortifying Bedroll yet.
My provisional list:
Invocations: Fell Flight, Flee the Scene, Dark One's Own Luck, Voracious Dispelling, See the Unseen, Entropic Warding.
-I'm thinking whether See the Unseen is a good choice with True Seeing on the cleric list of possibles.
I just barely cover my skill pre-reqs and that pretty much uses them all up. Feats are for pre-reqs (Spell Focus: Evil, Iron Will, Combat Casting) and I'm thinking about taking Extra Turning to go with DMM Extend and Persist.
The spell list is giving me trouble. This is for the Expedition to Castle Greyhawk, so enemies are all over the board. I'm only certain on taking Superior Resistance as one level 7 spell, but beyond that, I'm all the way up to level 8 spells, with the following slots:
0th: 6
1st: 6
2nd: 6
3rd: 5
4th: 5
6th: 3
7th: 2
8th: 1
Any help is appreciated in advance.
