Legendary Resistance (3/Day). On a failed saving throw an Anauroch Battleship can instead choose to succeed.

Greater Desertborn Magic. Anauroch cruisers have a Greater Desertborn onboard - sorcerers that belong to a mysterious cult that are supposedly born from the sand itself. As an action the cruiser can have their Desertborn tap into the magical weave of the great desert, choosing from the following options. The same option cannot be used twice in a row. Either before or after taking this action, the battleship can make a single Ballista attack and up to two Mounted Crossbow Barrage attacks.

Sandstorm. The Desertborn calls upon the sands which whip into a furious sandstorm in a 50 ft. sphere up to 100 ft. from the battleship until the start of its next turn. Any vessel in the affected has disadvantage on all attacks they make.

Greater Sandform. Up to three vessels within 100 ft., which can include the battleship, dematerialize and form sand visages of themselves until the start of the battleships next turn when they rematerialize. While in sandform the vessel is immune to all damage and can do nothing but move on their turns. If the target was unwilling they may make a DC 18 Wisdom saving throw at the start of their turn to rematerialize and take their turn as normal.

Greater Sandwalk. The Desertborn teleports the battleship and up to two allies within 100 ft. through the weaves of sand to a location up to 100 ft. in any direction, ignoring any obstacles or vessels in its path. The vessels emerge within 20 ft. of one another in any formation.

Multiattack. A fully crewed battleship can make up to three ballista attacks and two mounted crossbow barrage attacks.

Ballista. Ranged Weapon Attack: +5 to hit, range 160/450 ft., 1 target. Hit: 38 (8d6 + 10) piercing damage. A ballista has a -5 penalty for each size category of the target below Huge. Non-vehicle targets Large or smaller must make a DC 15 Dexterity saving throw, taking half damage on a success.

Mounted Crossbow (Barrage 2). Ranged Weapon Attack: +6 to hit, range 100/400 ft., 1 target. Hit: 32 (3d10 + 16) piercing damage. Non-vehicle targets Large or smaller must make a DC 12 Dexterity saving throw, taking half damage on a success. Barrage attacks do not trigger catastrophic damage.

Trebuchet (Recharge 5–6).  An explosive projectile is launched in any direction from the battleship to a range of up to 400 ft. creating a blast zone sphere with a radius of 20 ft. Each target must make a Constitution saving throw DC 16, taking 87 (6d12+48) bludgeoning damage on a failed save or half as much on a successful save. (Recharge: d6)

Sandform (1/Day). The Desertborn briefly dematerializes the battleship into a cloud of sand before rematerializing at the same position or up to 20 ft. away if it was rammed by another vessel. Ignore all damage from a single bludgeoning, slashing or piercing attack. This can be used after damage has been decided.

An Anauroch Battleship 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. The battleship regains spent legendary actions at the start of its turn.

Ballista Attack. The battleship can a ballista attack.

Mounted Crossbow Barrage Attack. The battleship can make a Mounted Crossbow Barrage attack.

Greater Sandwalk (2 Actions). The battleship can use their Greater Sandwalk ability. This nullifies the effects of any current Desertborn magical effects controlled by the battleship.
