Resolve (attack angle)
This angle of attack is not just the ability of the body to continue on, it is about the the ability to be put in situations that would hurt others, and remain safe while still attacking.
Resolve is the act of digging your heals in and dealing with the pain until your opponent gets too tired to continue.
Armor up.
