Dryads have the following traits:
Spell-Like Abilities: At will—entangle (DC 13), speak with plants, tree shape; 3/day—charm person (DC 13), deep slumber (DC 15), tree stride; 1/day—suggestion (DC 15). 6th-level caster. The save DCs are Wisdom-based.
Tree Dependent (Su): Each dryad is mystically bound to a single, enormous tree, or a copse of trees situated in one place (such as a lobby atrium) and must never stray more than 300 yards from it. Any who do stray from their trees become ill and die within 4d6 hours. A dryad’s tree does not radiate magic.
Wild Empathy (Ex): A dryad can use body language, vocalizations, and demeanor to improve the attitude of an animal. This ability functions like a Diplomacy check made to improve the attitude of a person. The dryad rolls 1d20 +10 (+6 species bonus, +4 Charisma bonus) to determine the wild empathy check result. The typical domestic animal has a starting attitude of indifferent, while wild animals are usually unfriendly.
