Claws of the umber hulk

Claws of the umber hulk was an arcane spell that would increase the size and power of the target's hands, to become akin to that of an umber hulk. The spell itself was incredibly painful, but could allow the target to cut through rock, or burrow underground.

Effects
If the target's stamina allowed for it, the target could cut up to 10 feet of pure rock or 6x that amount of soil, without resting. The casters new iron-strong hands could create a passable tunnel for the party. As well as its cutting and burrowing utility, the umber hulk claws could be used to attack targets, dealing high additional damage to their usual strength attacks.

Components
The only component required was the claw of an umber hulk.
