Throughout this game, the DC for identifying foe's defense, abilities etc has been so high that by the time I've got most of the info, I've over leveled them so much that they no longer appear. What gives? I have not neglected those skills...I have quite decent World, Arcana, Religion and Nature. I mean mid-level mobs with DC40 to identify abilities? It would be fine if it took a while to learn everything, but so far I rarely do until it's become useless information.

Edit: I am wondering, do the checks rely on distance/proximity to the party member that has that skill? Do I need to get that particular toon close to the mob before I try to eyeball them? If so that could be the problem, since most of the characters with highest knowledge skills are casters.
