This mechanical gauntlet is the creation of Professor Fezziwig Shacklebolt to serve a variety of purposes in the field and is powered by a spell focusing crystal.  As an action, pressing the multi-tool  button on the gauntlet's control panel produces any type of artisan's tool of your choice (see the "Equipment" chapter in the Player's Handbook for a list of artisan's tools). Whatever form the tool takes, you are proficient with it.

While wearing this gauntlet, you gain a +1 bonus to the spell attack rolls and the saving throw DCs of your spells.

While wearing this gauntlet, you have the ability to cast Mending and Shocking Grasp as cantrips and they do not count against your known spells list. 

Notes: Bonus: Spell Attacks, Bonus: Spell Save DC
