So yeah I was playing volibear this afternoon and was a good game but when we decided to kill baron and in fact we killed him my passive went up because I was on low hp but then I noticed that the passive didn't stop until I was at 100% hp then I jumped into the fight and the passive activated again over and over until I was at 100% hp again even though it was on cooldown but it still activated so I was an almost inmortal volibear

awwwww yeahhhhh!!!

So it's cool and all but I don't like abusing of bugs like this, I like fair play so yeah riot take a look on it and fellow volibears go and try while you still can
