Fighting it
You can attack once every 30 minutes. Each attack lasts 3 of your turns, which you play on the normal battle screen. Your damage comes off the shared HP.
You fight as your character: gear, potions and traits all count. Every attack starts at full HP, and the fight doesn't change your HP afterwards.
Attack with /boss in Discord, or from town in the Activity, which attacks your home server's boss.
It can't kill you. If it would, you end the attack at 1 HP and are Injured for 2 hours.
