So my friend and I are looking at doing a solo gestalt campaign starting at level 8. It's going to be relatively high-wealth, set in Eberron. Basically, the idea is that since our current DM makes a bunch of weird and arbitrary houserules(see my other questions), we want to take an opportunity away from that to explore the higher tiers and just what they're capable of. The general idea will be to powergame the crap out of my character and then throw me into situations any normal character shouldn't be able to ever deal with. Here are the specifics:
- "Epic fantasy" point buy
- More feats: Feats at 1, 2 and every even level (like fighter)
- 1.5 times normal wealth
- Starting at level 8
- The only thing off-limits is iterable infinite or near infinite cheese, like Gating Effritis for infinite wishes or stacking Time Stops for infinite rounds
I'm looking at either Artificer//Factotum or Wizard//Factotum, but I'm not sure which to go with. I was figuring that Artificer would give me more versatility with preparation than wizard, but I'm not sure if it's worth not having full casting on a per-day rather than per-dollar basis.
So the final question is: Given a solo campaign with in this situation, which build will be more usable, survivable, and able to efficiently complete the quests it starts out on? What would be my staple spells/items/general combat approach for each?
