Multiattack. Alderos makes two attacks: one with its bite and one to constrict.
Bite. Melee Weapon Attack: +10 to hit, reach 10 ft., one target. Hit: 22 (3d10 + 6) piercing damage.
Constrict. Melee Weapon Attack: +12 to hit, reach 5 ft., one Large or smaller creature. Hit: 19 (2d10 + 8) bludgeoning damage plus 17 (2d10 + 6) slashing damage. The target is grappled (escape DC 16) if Alderos isn't already constricting a creature, and the target is restrained until this grapple ends.
Lightning Breath (Recharge 5–6). Alderos exhales a line of lightning that is 20 feet long and 5 feet wide. Each creature in that line must make a DC 16 Dexterity saving throw, taking 66 (12d10) lightning damage on a failed save, or half as much damage on a successful one.
Swallow. Alderos makes one bite attack against a Medium or smaller target it is grappling. If the attack hits, the target is also swallowed, and the grapple ends. While swallowed, the target is blinded and restrained, it has total cover against attacks and other effects outside the behir, and it takes 21 (6d6) acid damage at the start of each of the behir's turns. A behir can have only one creature swallowed at a time.
If Alderos takes 50 damage or more on a single turn from the swallowed creature, Alderos must succeed on a DC 16 Constitution saving throw at the end of that turn or regurgitate the creature, which falls prone in a space within 10 feet of Alderos. If Alderos dies, a swallowed creature is no longer restrained by it and can escape from the corpse by using 15 feet of movement, exiting prone.
Alderos can take 3 legendary actions, choosing from the options below. Only one legendary action option can be used at a time and only at the end of another creature's turn. Alderos regains spent legendary actions at the start of its turn.
Swift as Lightning. Alderos makes a normal move.
Ball Lightning (Costs 2 Actions). Alderos launches a ball lightning at the furthest enemy. Random roll if tied for furthest. The enemy must make a DC20 Dexterity Saving throw, and take 4d12 Lightning damage, half as much on a successful save.
