Plate armor champ.

I had an idea: a champ that uses plates as a kind of armor.

One auto/ability would take off a plate instead of dealing direct damage and there would be maybe 5 plates on the character; the less plates they have the more likely they are to be hit. The plates would replenish after a while. They could also harden themselves and make their plates into basically one to protect themselves from plates falling off and after the duration is finished any missing portion of the full plate would fall off.
