Arcane demon

The Arcane Demon can be found in the 5th floor section C in the Slayerdungeon of Priffdinas. You need to have done the The Princess and the Warrior quest to access this area. This Demon is very weak against the Sword of Negatus which can be gain during the Burn in Hell! Quest. Without this weapon, it will be quite hard to hit him with melee or ranged weapons, allthough magic attacks work on them. They use melee and magic based attack.
