Ok, so I was playing a match online. We were getting curbstomped (long story short; I went with a good Erebus build and was doing OK in the beginning, our sedna refused to attack because he was roleplaying as the "pacifist," and our rook had no clue what he was doing and charged up to enemies between towers and hammer smashed. Lucky this was against AI, but one of them was a nightmare Ooze UB, so he was pretty much invunerable. >.< again.)
Anyway, I was getting hit pretty hard, and my teleport scroll was still on cooldown. So I go to grab a health vial. It kills me. My own health vial killed me. 
The thing is... I got gold and EXP from the kill. Well, I know I got the gold, it gave me the kill in stats, the message said "Milskidasith killed Milskidasith (+1200 gold) assisted by (2 computer players, +600). So I'm pretty sure I also got EXP from it, but I'm not entirely sure. I got everything else though.
So this basically means that an ereberus (with poison blood) can fight around the area, and instead of fleeing, gank himself for EXP and gold. Its a really useful denying technique... but also really cheesy and almost guaranteed to be unintended.
Also, why the hell does his own poison blood hurt him? >.>
