Branch of the Worldtree

Wand, spellcasting focus, rare (requires attunement by a spellcaster)
  Whether or not this branch truly came from the mythical Worldtree is unknown. However, it exudes potent, magical energy capable of manipulating plants and of great feats of healing. As it is used to channel a spell, the tips of its branches glow green-gold and the air is perfumed with the scent of mountain pines.
  This wand has 7 charges, represented by its seven green-gold leaves. When you expend a charge, a leaf withers and drifts to the ground. At dawn, new leaf buds unfurl and the wand regains 1d6 + 1 expended charges. If you expend the wand’s last charge, roll a d20. On a 1, the wand withers and petrifies, losing all magical properties.
  Regrowth. The wand can enhance your healing spells. While holding the wand, you can spend a number of charges equal to the level at which you cast a spell to increase the spell’s level by 1. The spell must heal a creature and cause no damage. You can’t use this property to increase a spell’s level by more than one level.
  King of Plants. The wand has power over other plants. While holding the wand you can cast the druidcraft cantrip at will. In addition, you can expend charges to cast the plant growth (1 charge) and tree stride (3 charges) spells.
