Dragonbait

Dragonbait is immune to disease.

While holding his holy avenger longsword, Dragonbait creates an aura in a 10-foot radius around him. While this aura is active, Dragonbait and all creatures friendly to him in the aura have advantage on saving throws against spells and other magical effects.

Dragonbait makes two melee weapon attacks.

Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 9 (1d8 + 5) slashing damage, or 10 (1d10 + 5) slashing damage when used with two hands. If the target is a fiend or an undead it takes an extra 11 (2d10) radiant damage.

Dragonbait chooses one creature he can see within 60 feet of him and determines its alignment, as long as the creature isn't hidden from divination magic by a spell or other magical effect.
