If you attempt to write enchant weapon or enchant armor (that you already know the appearance of) while confused, you will instead write the other one, even if you don’t yet have it identified.

Put a cap on the number of weapons in a stack that can be enchanted by a single enchant weapon scroll. Maybe 20 for ammunition and 5 or 7 for other stacking weapons like daggers. It’s odd that you can multiply the total amount of enchantment points you’re getting just by wielding a larger number of weapons.

If the scroll of enchant weapon targets a wielded bow but you have arrows quivered, or you are not wielding anything but have thrown weapons quivered, it may switch to enchanting the quivered ammunition instead.

Move enchant armor/weapon scrolls to the 200-zorkmid tier.
