- Magnet attract/repel happens just before this cast finishes; there is a quick moment to adjust when the telegraph appears
- Auto-cannons fire at the same time
- Getting hit by Auto-cannons or any Nerve Gas attack inflicts vulnerability up (10% per stack, 30s)
- North and south adds are always negative. West and east adds are always positive
- If you are solo, you will always be bound to the north add, which spawns behind the boss
- Use steel if you're not confident, so you can easily survive a hit from any of the Nerve Gas abilities
- A Doga demiclone will defeat the boss in about 10m45s with no player assistance
