You will find a cave appear in edgeville. To enter this cave you must have a double stacked membership of both gold and platinum. If your membership runs out whilst in the dungeon you will be teleported back to edgeville.
In the cave you will experience an additional boost in slayer XP of +0.5%
The members master is locked to level 75 slayer requirement. You will only get a task if you have the required slayer level to complete it. We will possibly release other masters in the future and adjust NPC's accordingly. You will get a massive 60 slayer points per task completion.
This will bring some of the end game slayer NPC's that you know and love that are currently locked to wilderness to non wilderness. However, their drops for rare items will be much lower, giving wilderness slayer still the advantage in terms of drops, but if you get bored of fighting for your life in wilderness at least you have another option instead of rage quitting. All ghostly npcs remain a wilderness only.
Feel free to message me in-game, on the forums, or on Discord with any questions or concerns you may have.
