"Sea Troll Queen", is a level; 170 boss in DreamScape 317. She lives in the water and she only can be attacked by Range weapons. Sometimes she sends "Cave Slimes" to hit you but the "Cave slimes" do not hit hard at all. She is the ruler of the Sea Trolls, and she attacks the Piscatoris Fishing Colony along with her Sea Trolls. She uses melee so it is advised to fight her directly with "Protect from Melee" (33-34) or (71-72) whilst wearing good defensive armour. She has an extremely high magic defense as well, so watch out.
The best way to kill the "Sea Troll Queen" boss is with a glock, or an Assault rifle. It is also recommended to pray "Soulsplit" (92 Prayer Required).
Since the Sea Troll Queen is a boss, it is included in the Soul System, converting all common and uncommon drops into souls. The Sea Troll Queen, along with all other NPC's in Dreamscape, drops the Infinity Key and immortal stone fragments
