Band of Wizardry

While wearing this ring, you gain one more 1st and one more 2nd level wizard spell slot. The wearer of the ring must be able to cast the leveled spelled before they can gain the extra spell slot.

For example, if the wearer of the ring can only cast 1st level wizard spells they only receive an extra 1st level slot. Once they are able to cast 2nd level spells they receive the extra second level spell slot.  

the rare variant of this ring grants an extra 3rd level slot in addition to a 1st and 2nd.
