Traits

5etools Note. While Galvan is not presented in an encounter in The Rise of Tiamat, the dragonsoul stat block has been provided here for ease of use, with optional alterations for the Blue Dragon Mask.

Special Equipment. Galvan has the Blue Dragon Mask.

Draconic Majesty. While wearing no armor and wearing the Blue Dragon Mask, Galvan adds his Charisma bonus to his AC (included).

Lingering Shock. If Galvan deals lightning damage to a creature while wearing the Blue Dragon Mask, that creature can't take reactions until its next turn.

Legendary Resistance (1/Day). If Galvan fails a saving throw while wearing the Blue Dragon Mask, he can choose to succeed instead.
