Try a level 150 fire mage with freeze skimmer, icecrystal pendant, DL gloves, mystic focus, void aggy grim of flame, firemage aggy bracelets, good skill rings, etc. Max fire attune, fire bolt, firestorm, and split the rest between fire lure and eshield. Swap fire attune rings, cast fire attune, then swap back to fire lure and fire bolt/storm rings.Warriors. There is a player on Epona named Allpashion...he can kill...any class. He is spear build, super luxed, super plat, and all hp. He has been un defeated.
For the duel, freeze first, run away, quickly swap skimmer for focus weapons, cast lure, fire bolt, firestorm. Warrior runs toward you, fire bolt again. He should be dead by now.
