You touch a stone surface or the ground, and call forth stone that shapes itself to your command. You can make any roughly shaped Small or Tiny item from the stone, including functional simple or martial melee weapons (for Medium or smaller creatures), possess magical durability to resist shattering or breaking.
Alternatively you can encase your limbs in stone, causing your unarmed strikes to deal 1d8 bludgeoning damage for the duration of the spell.
Items made this way lose any magical durability after one hour, and become easily broken if they would not normally be functional in that shape. You can have three items or effects created by this cantrip at a time, and upon creating a fourth the oldest one loses its magical durability and becomes easily broken.
