After you defeat the lost king you immediately face the lost queen however you lose all of your games and have to 1v1 her with the provided tek spear

Learned this the hard way, the tek spears do friendly fire so if theres multiple of you attack her one at a time, i did this with 2 others and they both died to friendly fire in just a few swings so i was left solo, be careful it can 2 swing kill your friends

When she points a single scythe at a player use the deflect with the tek spear or the attack will do loads of damage and sometimes one shot you even at 1000 hp on your player.
