Ramuh (Final Fantasy XIV boss)

Ramuh is fought as a boss in Final Fantasy XIV.

The Striking Tree (Hard)
This battle is fought as part of the Main Scenario quests added in Patch 2.3. Unlike other primals, Ramuh remains stationary in the center of the arena, over a logo of the Sylph banner.

Throughout the battle, he uses an attack called Thunderstorm. This targets up to five players and three random spots, marked by a ring of electricity. Players should try to avoid standing in overlapping rings to minimize damage. He also uses Chaotic Strike, which inflicts a long duration Terror effect that can only be removed by being shocked by Thunderstorm.

Once his health reaches 60%, he summons three Grey Arbiters in a triangular formation. These Arbiters must be defeated before his Judgment Bolt attack is ready, or else the party will be wiped out.

After Judgment Bolt, Ramuh resumes his earlier attack patterns. A new attack called Causality is used where two players are "tethered" by an electrical link. Both will take damage each time they perform an action, and can only be broken by one player grabbing three orbs throughout the arena to become electrically insulated.
