Exploration is right up my alley.I don't really like the unlocked potential feat but open minded is ok. I haven't yet given thought about travel. How would you like? Stay in relatively small area or explore the world?
Exploration it is then. Talented is also okay, pretty strong on D&D skill-feats, but still feasible.
Given that I like eberron pretty low-level, and normally you could get to M-I at level 4, so I think 4 is good. 5 if you really really want to start higher than 4.
Are you going to allow Sanity Resistance?Sure. And since this will be CoC inspired I'm going to use Sanity rules.
Yeah, but I'll also determine a bit differently what constitutes as a shock and what doesn't since eberron is afterall a fantasy-world. But your San.Res. is nonetheless equal to your level.
All righty. Is shock like horror or fear? Courage feat grants +4 bonus on all fear saves, Jaded feat grants +4 bonus on all horror saves [Ravenloft PHB].
How do you want to deal with stat generation?
