Ok, factotum questions:
Can I use retraining? I would like to have Able Learner before level 9, but it's an absolutely wasted feat for the first 8 levels (as Factotums gain all class skills anyway). So I would have to take an expendable feat at level 1 (perhaps FOI, or Improved Initiative).
I take it Iaijutsufocus IS ok? It won't be a damage king anyway, especially since without flaws the Inspiration Progression is quite slow. And I need to take EWP, and want to take Imp. Init and Knowledge Devotion. So no FOI before Lvl 6
.
Can I emulate Spellslots with UMD? This is sort of a late feature, since the checks are quite hard, but does allow some nice things with Runestaffs, like getting full CL on the spells cast from the runestaff. (The key, obviously, is emulating a "Class feature". But the wording is a bit unclear on the matter.)
Since this is Eberon, will action points be in? And how do they work? I'm an Eberron noob, so.... The SRD version sounds a bit overpowered.
