Damage Taken From Elements
Fights in distance.
Kill it quickly, since it can be annoying with its strong attacks, invisibility and fast self-healing. Area runes and spells are useful to use against this creature to cancel its commonly used invisibility.
Paladins should be 80+ with assassin stars before trying to solo, but it's better to kill with a partner if you're under level 100.
Knights should use chase opponent option and use Fierce Berserk and Great Health Potion when needed. Lower leveled mages should kill using Sudden Death Runes and Avalanche as well as Mana Shield.
