Enchanted Shrines

[[vL]Kp]

Can someone who can read code add input?

Without checking my notes, a quick re-read of the shrine code seems to suggest that it starts off by checking if you know at least 2 spells. If you don't, it skips the whole process. It's worth noting that if you learn a spell, have it reduced to level 0 by a shrine, and then hit another enchanted shrine, it is "known" for the purpose of this test, even though you cannot cast a level 0 spell.
