Suppose I have a sorcerer that takes IEH for a 2nd time with their level 19 feat, selecting New Arcana. The sorcerer already took GEH at level 17, so now EH feats go off the sorcerer's full level instead of level -2. Does this mean that I'd be able to select 3 9th level spells to add to my known spell list?
At 9th level, you can add any one spell from the sorcerer/wizard spell list to your list of spells known. This spell must be of a level that you are capable of casting. You can also add one additional spell at 13th level and 17th level.
As far as I can tell, since the only restriction is that the character must take spells of a level they're capable of casting, it would be legal to select 3 9th level spells if you could cast 9th level spells when you gained the ability. Anything pointing or suggesting this is incorrect?
