Finished learning Wisdom, no more spells?...

[Jack654]

Hi
I finished learning Wisdom lv.3 (as a Paladin), and I have learned many spells, without realizing the total was capped. I thought learned scrolls didn't "count" anymore. So I now have a lot more scrolls than my max, because I can still learn the ones I pick up, but I can't buy any anymore. What can I do? Is there something other than Wisdom that can allow me to expand the max scrolls, or is there a way to forget spells so I can buy new interesting ones?
