Nightmare Dungeons

Introduction

A Nightmare Dungeon is a harder version of a classic Ragnarok dungeon, filled with Elite Monsters. It brings back the old dungeons, at a much higher difficulty.

85 minimum Base Level for every party member
5 ~ 50 Nightmare Keys to open one, depending on the difficulty
24 h cooldown

How to get in?

Get Nightmare Keys (see below).
Go to the entrance of the dungeon: the Nightmare entrance is there.
Open the instance: the party leader creates it. A party of 1 player is enough, and each member must be at least Base Level 85.
