While flying, it can use its claws in place of one other attack.   Bite: Melee Weapon Attack: +7 to hit, reach 10ft., one creature. Hit: 11 (2d6 + 4) piercing damage.   Claws: Melee Weapon Attack: +7 to hit, reach 5 ft., one target.

The target must make a DC 15 Constitution saving throw, taking 24 (7d6) poison damage on a failed save, or half as much damage on a successful one.

The first Blisterwyvern was accidentally created when Republic scientists exposed tamed Wyverns to biochemical experiments early in the 2nd age. Although it would have been a wiser choice to exterminate them, Senator Eckhart ordered further study of the creatures in controlled habitats , while keeping the some of the military in the dark.   Biology: Blisterwyverns are a species of enormous, mutated bats, presumed to be Republic Attack Wyverns.[9] The gargantuan creature has retained its ancestors' stinger, membranous wings, allowing it to fly and soar through the air, and noxious poison. However, it has grown multiple spines along its tail, lost much of its scales, developed a beak to replace its old jaw, and evolved to become the carrier of a plague which converts any infected living being into the the Blisterseared. Despite their size, Blisterwyverns possess considerable agility, and even when grounded they can leap several times their body length in one bound. Despite the behavior of their progenitors, Blisterwyverns are not averse to cooperatively hunt in groups
