Seed of the Old Forest

Wondrous item, uncommon

This preserved seed is a relic of an ancient elvish tree from before the world fell, meant as a way to revive the land. When you plant it as an action, the seed grows a sapling after 1 round. 8 hours later, the sapling bears 8d8 goodberries as the spell goodberry. Once the berries have been picked or after they lose their potency, if a Doomgate remains open in the same mortal world, the tree withers and dies unless strengthened by a spell such as plant growth or awaken. When the tree dies, roll a d20. On a 20, the withering sapling leaves behind another seed of the old forest which can be planted again.
