The power of the gauntlets allowed Dame to take the power that the dead contained. Somewhat similar to the demonic extraction technique, but it was more than that. It didn't just take the Qi energy, but almost took their spirit along with the traits of their powers.
What Dame had been using was the specially crafted body that Simyon had built up. That power was running through his body thanks to the gauntlets. The thing was, the power wasn't a simple swap either. It was added to Dame's, so his already hard body of a hybrid was amplified due to Simyon's power.
On top of that, he also had a surge boost with Simyon's Qi. This was allowing Dame to focus on everything but defense. He had embodied what Simyon was trying to be, the perfect shield, an indestructible force, and he had proved it by withstanding the entirety of the attack that was made by Garlon.
