The Swamps of Morytania in Old School RuneScape will become even more scarrier with the launch of The Nightmare of Ashihama, a new boss which is available starting today. You can fight the boss with up to 80 players at a time, which has all new combat mechanics that are all new for RuneScape.

Rumored to be feeding on the dreams of the innocent towns folk, this monster is supposed to grow stronger as time passes. This requires a group to conquer, which makes the challenge even trickier. The monster is apparently too powerful to be beaten up alone and is rumored to need about 80 players at a time to defeat. This is a challenge like nothing players have seen before in the Old School RuneScape.

The Nightmare is apparently too difficult to handle alone, and although technically you can battle this monster solo mode, the chances of your success are as thin as a sheet of paper. According to the studio, only the best of the very best can defeat this monster collectively. This is how difficult this monster is expected to be.

To encourage players to participate, the studio has even announced that players who participate will get their own personal rewards to stop players from scrambling all over the loots. There are so many rewards available for grabs, and when the beast dies, there is a chance of dropping a unique item! According to the studio, the more damage inflicted, the better the chances of unique loot.

The Nightmare of Ashihama is the first exclusive group boss for Old School RuneScape which focusses on co-op. The new boss will be hidden in de catacombs of the Sisterhood Sanctuary in Morytania. The difficulty of the boss will scale with the size of the group and only the best of the best will be able to complete this fight alone. Each player which completes the fight, will get a reward, so don't hurry to get your loot.
