Mods/The Aether/Valkyrie Queen

The Valkyrie queen is the boss in silver dungeons. To fight her, you must give her 10 victory medallions and right click on her. Then, you will be able to strike. Like normal Valkyries, she can teleport behind you and hit very hard. She appears icethings, that look alike to those in the gold dungeon, and it explodes (sometimes in your face). The dart shooters and the bows are recommended to kill the Valkyrie queen. Upon death, she will drop a golden sword and a silver key. You can open a locked chest by right clicking on it with the silver key. What you can find in the chest is holly swords, lightning swords, neptune pieces of armor and the Regeneration Stone.
