Multiattack

The bereginyas makes two claw attacks. If both attacks hit the same target, the target is grappled (escape DC 12) and the bereginyas immediately uses Smother against it as a bonus action.

Claw

Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 9 (1d8 + 5) slashing damage.

Smother

If the bereginyas grapples an opponent, it extends a semi-solid gaseous tendril down the target's throat as a bonus action. The target must make a successful DC 14 Strength saving or it is immediately out of breath and begins suffocating. Suffocation ends if the grapple is broken or if the bereginyas is killed.
