Health: 33M
This boss has no Hardmode.
During the fight there will be additional enemies: Harpy Stormweavers and Harpy Windcallers that attack at range. They should be taunted and ideally stacked on the Sail Ripper.
Sail Ripper will periodically fly around the arena, and right after the flight it will start channeling a lightning attack that needs to be interrupted as soon as the boss is reached before it damages the whole team.
On a timer, a random player will receive Storm Cell, and a lightning aoe will be centered on the player until they deposit it on a hollow circular area (this is commonly known as donut mechanic). Note that players in the lightning around the player affected by Storm Cell will take increased damage from the lightning.
During the fight, everyone needs to stay under the shelters to avoid gaining stacks of lightning (Building Static). They act the same way as described in Boss 2 - Reef Guardian.
