The Queen Percht
You can fight the queen with up to 5 players, once every 20 hours. The fight is very easy and there is practically no danger of dying, a team of players around level 100 should be enough to do so.
To defeat Queen Percht, you must first unfreeze it.
To do this, you need to follow these steps:
1. As soon as you pull the lever, you will be in a small room with a fire and a green vortex. Use the bonfire and a torch will appear in front of it, pick it up; 2. Step on the green Vortex and your appearance will change to a Leaf Golem; 3. Go down and then quickly go to the other side of the dungeon. Do not go north. When you step near the wall, a Rush Wood tree will appear. Use it 5 times, each time a piece of wood appears in front of the tree, pick it up. 4. Go south, where there will be a small bonfire. If it is not lit, use your torch and light it. Start using the wood at the campfire. 5. After using all the wood, go back to the west side, become the Leaf Golem and repeat this process until a Warm Fire appears. 6. When the Warm Fire appears, the bonfire will stop burning, use a torch again (the torch lasts only about a minute, then you will also need to constantly pick up a new one). So use the bonfire and you will start to burn. 7. Launch the Warm Fire to the north, but be careful because the Percht Minions will try to kill you. Also avoid the ice beams that come from the north of the room. Warm Fire will explode and deal damage to Percht Queen. 8. Repeat the above process until Percht Queen is no longer frozen and can be killed by players.
There are 3 important things to keep in mind:
1. Never walk to the north of the room if you are not turned into a man on fire. You will instantly "freeze" and be teleported out of the battle, with no way to get back.
2. If you do not get near the campfire to the west every few minutes, you will begin to feel cold (You are cold.). If this message appears, quickly go west and walk near the campfire to warm up.
3. To receive the draw, the player must have attacked Percht Queen. Once it is no longer frozen, it will die quickly, so the entire team must be told to do damage to it.
4. After defeating Percht Queen for the first time, you will receive the Percht Raider Outfits.
