You have developed traits similar to those possessed by a will-o'-wisp, granting you the following benefits:

Ability Score Improvement. Increase your Dexterity by 1, to a maximum of 20.

Will-o'-Wisp Form. As a bonus action, you can transform into a ball of light until the start of your next turn. When you transform, any equipment you are wearing or carrying is merged into your new form. While transformed the following changes apply to you:

• Your Strength score becomes 1.
• Your Dexterity score increases by 5, to a maximum of 28.
• Your walking speed becomes 0.
• You gain a flying speed of 50 feet, and can hover.
• You gain immunity to lightning and poison damage.
• You gain resistance to nonmagical bludgeoning, piercing, and slashing damage.
• You gain immunity to the grappled and restrained conditions.
• If a creature within 5 feet of you dies, you can use your reaction to regain 3d6 hit points.
• You can't wear or carry anything.
• You can move through other creatures and objects as if they were difficult terrain. You take 1d10 force damage if you end your turn inside an object.
• You shed bright light in a 5- to 20-foot radius and dim light for an additional number of feet equal to the chosen radius, while you aren't invisible. You choose the radius when you enter this form.
• As an action, you can make a melee spell attack against a creature within 5 feet of you. You use your Wisdom modifier for the attack roll. On a hit you deal 1d8 lightning damage. The damage increases by 1d8 when you reach 5th level (2d8), 11th level (3d8), and 17th level (4d8).
• As an action, you can become invisible until the start of your next turn.

You can use this feature a number of times equal to your proficiency bonus, and you regain all expended uses when you finish a long rest.
