Strategy
Since the Melee poisons you, it's better to keep distance as a Mage or Paladin. Knights should try to trap him and use Melee, Brutal Strike and Berserk. Make sure to keep an eye on your Skills so you don't waste lots of Mana on your attack spells when it has lowered your skills. Try to corner them because when they use Haste they are extremely fast, and you won't be able to outrun them. A good strategy to kill these as a Mage at the Fenrock spawn is to Summon a Fire Devil or another creature immune to Fire Damage and let it block the ranged attacks while you use Ice Strike and Strong Ice Strike. Depending on your level you might want to use Magic Shield.
