Conjure Brick in a Sock

Everyone knows that a wizard never leaves their hat behind. Only slightly less well known is that they never leaves their socks either.

Taking your sock in hand, summon a mass inside the sock roughly equivalent to a brick. This Sock becomes a melee weapon you are proficient in that deals 1d8+ Spell Casting Modifier magic bludgeoning damage. If you are below half your total hit points, add an additional 2d8 to damage.

If cast using higher level spell slots, increase AC by 1 while weilding the Sock for every level above 2nd.
