I figured his fighting style after multiple failed attempts over the Very Hard setting. He has some sword fighting skill but is useless when in tight quarters. I was able to use the dodging system as a fighting system during sword combat which confused ODA during fight sequences where he believes he would land his attacks but nothing but soft handed hits. I was able to easily push ODA away as he hates to be hurt. Once he was under 50% you saw a different side of ODA one that prefers running and hiding over direct combat and the use of his AI driven dual hand guns which he shoots aimlessly in the air relying on the homing effectiveness. But the area plays out like a school yard fight in the jungle gym. If you dodge ODA and find his healing hiding spots with the use of some grenades you will quickly find ODA is quite defenseless once pressured back. During some of the encounter with ODA I began to also climb and traverse some of the stage in pursuit of ODA which also trigger his flight instead of fight. I let him live at the end of the fight sequence because I seek another rematch with him he has forced me to develop my Character much much more. My Avatar was not prepared for the fight sequence with ODA but after the interaction I was left with an impression that the sky is the limit for enhancements that curve the battle in ones favor. I was really kicking ODAS butt hard it took much longer to see him die then I think it should but we shall see.
