For this boss, I were on turret duty as well as passenger of demolisher. Below are tips from my perspective:
- Start as passenger of chopper
- Jump to demolisher after first passenger is thrown to Flame Leviathan for first Systems Shutdown
- Defeat the Guardians of Nature when they are spawned
- Top-up Liquid Pyrite when less than 50%
- Ignite Tars & Damage Flame Leviathan
- After first Systems Shutdown, Load into Catapult and been thrown to Flame Leviathan
- Take Out Those Turrets, start second Systems Shutdown, go back to chopper and repeat the same.
