In order to finish your last task in the Pankration, you must return to Paios and defeat the reigning champion, Dorieus. You can choose to apply the oil on your body before the fight, however this will only result in aesthetic differences. The fight is fairly simple but you should be careful to avoid any special attacks that Dorieus attempts to execute. Each time his body glows red you should attempt an evasion or block. Quickly respond with a series of light and heavy attacks to inflict the most amount of damage before he attempts to execute another special attack. It will not take long to wear down his health using this tactic.
