Tree Shape (2/Day). Over the course of 1 minute, Derwyth can magically transform into a Huge or smaller tree and remain in that form for 24 hours or until she ends this transformation early (no action required). Her equipment melds into her new form. While in this form, her Armor Class is 16, she has the incapacitated condition, and she can't move or speak.
Spellcasting. Derwyth is a 4th-level spellcaster. Her spellcasting ability is Wisdom (spell save DC 12, +4 to hit with spell attacks). She has the following druid spells prepared:
Cantrips (at will): druidcraft, produce flame, shillelagh
1st level (4 slots): entangle, longstrider, speak with animals, thunderwave
2nd level (3 slots): animal messenger, barkskin
Quarterstaff. Melee Weapon Attack: +2 to hit (+4 to hit with shillelagh), reach 5 ft., one target. Hit:3 (1d6) bludgeoning damage, 4 (1d8) bludgeoning damage if wielded with two hands, or 6 (1d8 + 2) bludgeoning damage with shillelagh.
Derwyth lives in Cernant Valley—a forested basin at the foot of the Tegefed Mountains—along with many animals, most of which are small woodland creatures. These animals act as Derwyth's eyes and ears, quickly bringing her news of events in the wood, particularly the arrival and actions of strangers. The creatures also carry messages to more powerful Beasts in the valley that sometimes come to Derwyth's aid.
