[@Lugubrious] For Centurion's level 3 power, I was thinking he could get the ability to heal off kills. He has the feat in the game called Body Count. The bigger the enemy, the more health he gets back. That way it gives him more sustainability. Does that sound fair/ balanced to you?

If not, maybe his new ability is just being able to summon and create a new, heat resistant gladius that matches his size. 

I'm not sure which one.

That sounds balanced. I would go with Body Count, since he can just be made a new gladius
