Gigant

The gigant has advantage on saving throws against spells, and any creature that makes a spell attack against the gigant has disadvantage on the attack roll.

The gigant makes one Mandibles attack and two Talons attacks.

Melee Attack Roll: +13 to hit, reach 10 ft., one creature. Hit: 21 (4d6 + 7) slashing damage, and the target has the grappled condition (escape DC 17). Until the grapple ends, the target takes 21 (4d6 + 7) slashing damage at the start of each of the gigant's turns. While the gigant is grappling a target, it can't use Mandibles against other targets.

Melee Attack Roll: +13 to hit, reach 20 ft., one target. Hit: 17 (3d6 + 7) slashing damage, and the target is pulled 10 feet straight toward the gigant.

The gigant releases magical dust from its wings in a 30-foot cube. Each creature in that area must make a DC 19 Constitution saving throw, taking 45 (10d8) poison damage on a failed save, or half as much damage on a successful one. On a success or failure, the creature has the poisoned condition for 1 hour. While poisoned this way, the creature can't regain hit points.
