Proficiency required: Carpenter's or Woodcarver's tools

Apprentice

Even a simple piece of wood is an implement of destruction in the hands of those who know the secrets engraved within wood. You can cast the shillelagh cantrip, using Intelligence as your spellcasting modifier.

Journeyman

Your touch can cause flesh to gain the resilience of strong ironwood. You can cast the barkskin spell, using Intelligence as your spellcasting ability modifier, though the minimum AC granted is equal to 15 + your Proficiency bonus. You regain the use of this ability at the end of a long rest.

Master

In times of need, you can cause sharp wooden stakes to grow from the earth full of barbs and splinters. You can cast the spiked growth spell twice, using Intelligence as your spellcasting ability modifier. You regain expended uses of this ability at the end of a long rest.

Grandmaster

Your knowledge of trees and their bounty gives you an innate bond to worked wood. You can cast the tree stride spell, using Intelligence as your spellcasting ability modifier, though rather than trees, you can move through and out of wooden doors. You regain the use of this ability at the end of a long rest.
