You can pass through nonmagical plants without being slowed or damaged. In addition, you moving through nonmagical difficult terrain costs no extra movement.

You can read, write, and speak Common and Sylvan.

You gain +2 to Consitution, reflecting the hardy nature of Dryads, and +1 to Charisma, reflecting their ethereal nature. If you are using flexible ASI rules, these can go into any stat of your choice, as long as they don't overlap.

Your connection with nature grants you an innate understanding of the natural world. You gain proficiency in Nature and Survival.

If you're playing with flexible proficiencies, you may swap these for any other skill.

You have advantage on Saving Throws against being Charmed, and magic can’t put you to sleep.

Though your ties to the forest have been severed, you retain the magic of your ancestors. You know the Druidcraft cantrip. Once you reach 3rd level, you learn the Entangle spell and can cast it once as a 2nd-level spell. Once you reach 5th level, you learn and can also cast the Barkskin spell once. You must finish a long rest to cast these spells again with this trait. Charisma is your spellcasting ability for these spells.

Your magical nature affords you some resistance to harmful magics. Once per day, if you fail a saving throw against a spell or magical effect, you may choose to reroll it. You must keep the second result.

While most living creatures don't like being set on fire, Dryadines are particularly susceptible to fire damage. Whenever you take fire damage, take an additional die of fire damage.
