Burnout Enders Question

I am trying to pick up Cinder. I love his cocky attitude and his bad ■■■ one liners. I am having a hard time understanding the burnout enders. I understand that when a part of the of opponents legs or arms are on fire and they use moves that require these body parts. It fans the flames and creates potential damage. How do I cash out this potential damage into actual damage?

Do another ender.

Try and do another combo into an Ender to cash it out. Once you do that, all the white damage as well as the regular damage will come out. Cinder hurts when you have a lot of potential damage.

You have to open them up with another combo and do another ender to cash out the damage.

thanks guys I appreciate it
