League of Legends (LoL) Question: What is the easiest lane to get pentakills?

A pentakill is something you can practically only get during teamfights, so it doesn't really matter what lane you played in before the teamfights started. What does matter though, is whether you are capable of kill securing.

Supports probably won't be able to steal five kills in a row. Swain probably won't be able to steal five kills in a row. Katarina and Darius like mentioned by others, will be able to secure kills.

Furthermore, the champion needs to be mobile, enemies may flee after a fight is lost or the fight may take place in a big area, it's important to be able to quickly move from one kill to the other.

I disagree with the Cassiopeia recommendation. She can get a penta in the sense that she can probably take on five enemies if they would run at her in a row, but she doesn't pack the necessary burst to steal five kills.

I think that in the end most champions able to get pentas more easily are usually played at the mid lane though.

Since others have already pointed out that bursty mid laners are your best bet, I'll offer up a couple other suggestions for champs.

Akali's really good at getting Pentas providing you know when to jump (literally) into the fight. Since she gets a free ult for every kill or assist she gets and has otherwise generally low cooldowns, she can ninja-kick her way from target to target and burst them down pretty quickly. As with all champs, though, it all depends on how good you are at executing her combo.

Karthus is capable of getting Pentas as well...and not just with getting that super lucky R in the middle of a match that just happens to finish off the entire enemy team (I've only pulled that off once :P). Getting them with Karthus generally relies on proper utilization of his passive during a team fight. It requires picking the right moment to go full kamikaze and dive into the fray, pop your ult the instant you die (which should, if you timed your death well, nab a couple kills), drop the wall and start popping Q's. If your positioning is good and you're good with aiming your Q's, you can walk away with a Penta, or at least some level of multi-kill.

Katarina any role. Hue.

But generally speaking, Mid or ADC. Some Top ( Darius, as mentioned) but lots of top-laners are more front-liners that get the fight started (junglers are similar). ADCs dish out the DPS, and the clean-up champs are more often Mid.

Most likely to get them is either Mid or Top. If you aren't into Darius I would extremely recommend you picking him up if you feel like getting multi-kills and 1v2-ing in lane. His zone is extremely good, his combo is absolutely deadly and resets, providing an unlimited amount of damage given that you execute with your ult. His problem is kite, which, in lower elos, people tend to not do very well, so your left with a broken champion. I got a penta-kill my 4th game playing with him. For mid I would say Cassiopeia. As long as they are poisoned and you have a full mana bar, you have an insane amount of DPS and you never have to wait on cooldowns. Generally champions with high dps end up getting the pentas, since they have an endless amount of damage, unless you are a super fed assasin. Most of the time multi kills are dependent on being at the right place at the right time. Heavy resest champions, and DPS champions are your best friend for getting the pentas.

I would say mid because you're playing solo in the lane and you get a lot of cs if you have wave-clear abilities which most mid laners have. I actually suggest using katarina to get pentas because if you have the right start she is a huge snowball and can 1v5 easily and has no skillshots whatsoever.

Champions that have some sort of reset on their damage source, or mobility spell which includes but is not limited to (I think): ( Kha'Zix, Katarina, Akali, Darius, Kalista, Tristana and Master Yi.

Also, champions who do not rely on mana ( Garen, Shyvana, Riven) are capable of getting pentakills more often than others.

Champions with low cooldown mobility or gapclosers ( Tryndamere, Kassadin or champions with auto attack resets like Xin Zhao are decent at getting penta's with because they have a bit of sticking power.
