Call of the Styx
Actions
Call of the Styx (1/day). The balor calls upon the deathly cold waters of the River Styx to drag the souls of the fallen to the lower planes. The balor creates a line 60 feet long and 5 feet wide filled with the freezing, life-leeching waters of the Styx. Each creature in the line must make a DC 20 Strength saving throw. On a failure, a creature takes 72 (16d8) cold damage and is pulled up to 60 feet towards the balor. If the creature fails by 5 or more, it is also Frozen (escape DC 20). On a success, a creature takes half as much damage and suffers no other effects. A Frozen creature is partially encased in ice. It has a movement speed of zero, attacks made against it are at advantage, and it is vulnerable to bludgeoning and thunder damage. A creature may use an action to perform a DC 20 Strength (Athletics) check to break the ice and end the condition. The condition also ends whenever the creature takes any bludgeoning, thunder, or fire damage.

Reactions
Fiendish Cackle (1/day). Whenever a creature the balor can see fails an attack roll, ability check, or saving throw, the balor can use its reaction to cackle maniacally.

Bonus Actions

Actions
Fiery Teleportation. The balor disappears and reappears in a burst of flame. It teleports up to 90 feet to an unoccupied location it can see. The balor may choose to bring one friendly creature within 5 feet or a creature it has grappled with it. Each other creature that did not teleport within 10 feet of the balor either before or after it teleports must make a DC 18 Dexterity saving throw. On a failure, it takes 49 (9d10) fire damage.
