So, I've probably killed about a dozen Momentus's in the Wild so far. And, of course we get another spawned, so I'm ready to go kill it the same way I've killed the other 12. I go in, and right as he sucks me in, I get auto-killed?? This has not happened to me ever, and it is quite frustrating because I've been able to kill all the others with no trouble. I even put Iron Armor on (I didn't use armor on the other ones) and still no difference. I'm quite confused...it's whenever he sucks me in, I just die automatically. Anyone got an explanation?
