Li Shenron said:41 more spells a "slightly larger repertoire"?![]()
41? Oh, I see. You're taking this hypothetical wizard all the way to 20th level. In that case, yes, 41 is only slightly larger, as that 20th-level Wiz will easily be affluent enough to obtain most of those 41 spells on his own.
Learning 2 extra spells per level sounds about right. Certainly any less wouldn't be worth a feat.
