The third Blood Sentinel encountered in Infinity Blade II is an Exo-Pilot. He wears the EXO Helm and EXO Armor. Instead of being Deathless, he is mortal, and does not care about the Deathless, his duty is to uphold the great pact, and defend this tower from all who would violate it. Siris does not directly fight him, but fights his machine, the MX-Goliath, instead. During the first encounter, you meet him at level 100.
