Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 6 (1d6 + 3) piercing damage.

Breath Weapon (Recharge 6)

A light drake can breathe a 30-foot line of brilliant white light. Each creature in that line must make a DC 13 Dexterity saving throw. On a failure, a creature takes 5 (2d4) radiant damage and is blinded for 1 minute. On a success, a creature takes half the damage and isn't blinded. A blinded creature can make a DC 13 Constitution saving throw at the end of each of its turns, ending the effect on itself on a success.
