Okay, made a bunch of changes:

- Sorted out spellcasting. If an artifact grants "Spell Slots", those are cast at the max level of spell you know (up to 5th) and aarefresh on a short rest; basically, pact magic slots. if you gain a Labeled spell slot (e.g. 6th level spell slot) that one refreshes on a long rest.
- Magical weapons each have a non-cumulative Magical bonus progression, and do not stack with any bonuses granted by virtue of an item gaining the abilities of another magical item.
- formatting got better.
