Legendary Resistance (3/Day). If the Riptide fails a saving throw, it can choose to succeed instead.

Magic Weapons. The Riptide's weapon attacks are magical.

Progressive Damage. When the Riptide is reduced below 600 hit points, and also when it falls below 300, its core systems take damage. The Riptide's attacks take a -2 penalty to hit, its AC is reduced by 1, and its speed is reduced by 10 feet. Additionally, the creature that reduced the Riptide below either threshold immediately rolls a d6. One of the Riptide's Nova Core functions is damaged and can't be used until the Riptide regains all its hit points. The system that fails is dependent on the roll (1-2: Might, 3-4: Vigilance, 5-6: Speed). If something other than a creature brings the Riptide below these thresholds, the DM rolls a d6.

Actions Multiattack. The Riptide makes three attacks with its Farsight Blade or Arc Welder. Farsight Blade. Melee Weapon Attack: +16 to hit, reach 20 ft., one target. Hit: 19 (3d6 + 9) slashing damage. Arc Welder. Ranged Weapon Attack: +16 to hit, range 300 ft., one target. Hit: 22 (4d10) lightning damage. Nova Core. As a bonus action, the Riptide activates its Nova Core to bolster some of its capabilities. The Riptide takes 22 (4d10) lightning damage, due to the instability of the device, and gains one of the following benefits until the end of its next turn: Might: The Riptide doubles the number of attacks it can make with its multiattack action or legendary action. Vigilance: The Riptide raises its shield, gaining a +3 bonus to its AC and any saving throws it makes. Speed: The Riptide doubles its walking and flying speeds. The Riptide then can't use this action on its next turn.
