Bishop vs Beast in AQ

Macombering

I just took my 5* Bishop into Map 3 Alliance Quest. I brought him against Beast thinking it would be easy enough for me to test some abilities. I used Bishop’s Prowess charge build up using well timed blocks until I had 9 Prowess charges. I then went to use them to heal and when I did Beast’s Power Meter shot up to full power! I cannot find anywhere in the information on these champs that would cause this to happen. I assume it is a bug.
