Fists of Lightning and Thunder. Digital Casandalee’s fists strike with the power of a thunderstorm. For any given slam attack, a Casandalee can choose whether that attack uses lightning or thunder. A lightning attack deals an additional 3d6 points of lightning damage, and the resulting flash blinds the target for 1 minute (Constitution DC 18 negates the blindness). A thunder attack deals an additional 3d6 points of thunder damage, and the resulting thunderclap deafens the target for 1 minute (Constitution DC 18 negates the deafness).
Immutable Form. Digital Casandalee is immune to any spell or effect that would alter its form.
Magic Resistance. Digital Casandalee has advantage on saving throws against spells and other magical effects.
