Arvesta’s Thorn (Exalted)

This small dagger looks like an old gnarled branch at first glance, but close examination reveals a finely pointed tip and serrated edge that is obviously a product of exquisite craftsmanship.

While Attuned to this dagger you have a +2 bonus to attack and damage rolls made with this weapon.

While attuned to this weapon, As a bonus action, you can Invoke the ability of this dagger to grow hardened tree bark on your body as armor (As per the Barkskin Spell). This ability also grants the creature wearing this armor resistance to nonmagical bludgeoning, piercing, and slashing damage

As an action, You can stab this dagger into any loose earth or soil and speak the command word to rapidly grow a 10ft tall tree in that spot. All normal plants in a 100-foot radius centered on the tree also become thick and overgrown causing a creature moving through the area to spend 4 feet of movement for every 1 foot it moves.

If you leave the dagger in the same place over the span of 8 hours, you enrich the land. All plants in a half-mile radius centered on the tree become enriched for 1 year. The plants yield twice the normal amount of food when harvested. As long as the dagger remains in the same spot, this tree will stay healthy and grow normally. If the Dagger is removed the tree will rapidly decay and die, though if the surrounding plant life was enriched it will remain unaffected.

The Dagger has 30 Charges for the following Properties. It regains 3d6 + 2 expended Charges daily at dawn. If you expend the last charge, roll a d20. On a 20, the dagger regains 1d12 + 1 Charges.
