i would say mine was more skill and brainyness but when i was chacing someone down as diana last free week they turned a sharp corner(the one near purples golem brothers), they had low health but there was no way i would be able to catch up because i was quite a way behind so i aimed my skillshot thingy into the dark around the corner and got the kill.

Swapping an enemy into spawn with Urgot.

I was playing Ashe and I had just teleported back to based when a team fight broke out waaaaay up at the top of mid lane. I knew there was no way I could get there in time to really help, but I figure, what the hell, I'll ult and shoot an ice arrow up there and maybe it'll somehow hit and stun someone long enough for one of my allies to do some damage. Can't hurt, right? So I shoot it off randomly into that general area and start jogging up lane. About four or five seconds later I hear "You have slain an enemy!"

o.O Really?

Never even saw what happened.

playing teemo and was getting chased by a tryn and irelia, they ran over so many shrooms they got beat to death by super minions and casters. i got away with 13 hp.

another is when i was play viktor i managed to last hit with Q on a Tf which saved me from a lux's Ult.
