Silvanus's Boon

You are granted enhanced natural power by the god Silvanus, which heightens your reflexes and accentuates your personal nature. The divine magic that you are imbued with causes you to grow taller. When you gain this feat, roll 3d4. You grow a number of inches in height equal to the roll. You can increase your Dexterity and Charisma scores by 2 and also increase your maximum for those scores by 2. In addition, you learn the wall of thorns spell, which you can cast once without expending a spell slot. You regain the ability to cast this spell in this way after 10 days. You can also cast this spells using spell slots you have of the appropriate level.

Charisma is your spellcasting ability for this spell, and you cast it at the lowest possible level.
