Potential Tahm Kench bug
i've had some instances where I was swallowing a minion or jungle monster and spit it back out immediately. but then the minion stayed at that magic pixel of health and refused to die.
the first time it happened was when i was trying to kill the krugs on the red side.** i was mashing Devour on the big Krug to kill it but suddenly found that he was staying alive like he had Tryndamere's ult, but without the yelling.** I was low on health at the time, and was a little preoccupied with trying to kill the Krug. So Tahm Kench got executed.
it happened again when i was clearing a wave in mid with an allied Twisted Fate. I was mashing Devour on the last minion and then noticed Twisted Fate was swinging more cards at the minion than he should. Needless to say the Twisted Fate player was as baffled as I was.
So, a warning to Tahm Kench players. Don't mash Devour.
