RChu1982: You can farm Rapax Corpses (it's not that hard, maybe a decent night of drinking to offset all those non-drops).
So, how would you go about doing that, assuming Ironman and no force quits or intentional crashes/getting crushed?
Even ignoring this issue, it's still tedious, particularly since, if you're reloading, you don't get to keep any XP or skill increases while doing so.
(Also, assuming you're referring to drinking alcohol, not everybody does that.)
RChu1982: The Priest and Bishop sacrifice the Dagger skill (which is unholy)?
But can still equip the Canezou Dagger because it's a quest item. (Then again, said dagger appears to be holy to the Rapax.)
RChu1982: You're expected to get through the Mountain Wilderness, as well as the Rapax areas, only to get to AP, and have to fight Pee Wee (optional), as well as the Souleater, Djinni of the Clouds, etc. all at level 20 or so? You would have a hard time, especially against the Dark Savant.
Level 20 or so (with 20 being a lower bound) is what an experienced player could be expected to reach.
A new player who takes their time will be around level 25.
The Dark Savant's high level doesn't affect your ability to hit and damage him with physical attacks. Also, the enemies he summons aren't as high in level. Also, the Dark Savant isn't meant to be easy, even if he actually is in practice.
I find myself doing the Rapax areas in the teens, and I don't really have much of an issue there, aside from the fact that this is the point of the game where spell damage isn't as useful, making encounters less fun from that standpoint. (Well, that and Vi, if you're using her, being less effective in this part of the game, not to mention needing to be smuggled in (via the T'Rang teleporter, for example).)
(I tend to do Rapax areas before Bayjin because the rewards are greater, particularly with Ferro being there.)
