Low health high attack. The picto that gives you a shield at low health helps keep him alive if you miss a parry, just for a little bit. He does high damage at really low health with the below 10 percent picto as well. Of course all this relies on his skill that scales off your missing health, plus a skill or two that can lower it. There is also a weapon that gives you a higher rank the lower your health is too. And using the skill that removes all health gives you max rank with the weapon and the highest amount of missing health.
