These gauntlets give the user a +1 to spell attack and spell saving throws.
This pair of rich silk gloves are guarded by an enchanted mithral shell that sporadically releases arcane power. You can use the gauntlets as a spellcasting focus while wearing them, when you cast a spell using a 1st through 5th level spell slot, you can choose to roll a d6. If you roll a number on the d6 equal to or greater than the spell's level, the spell draws on the magic within the gauntlets instead of your own and is cast without expending a spell slot. The slot must be of a level you can normally cast. The gauntlets can provide up to 5 levels worth of spell slots in this way each day and no two slots can be the same level.
