Not sure if this has been noticed, but when you miss with a spinning fire blossom, it refunds your Chi. In addition, it seems to reset the timer on the decay of the Chi as well. Because of this I've been capping my Chi between fights with expel harm, and just running around spamming spinning fire blossom to keep capped on Chi. I know the benefit isn't huge, but is this an intended mechanic or possibly an exploit?
