How do Pentas work EXACTLY?
Played an Ez game yesterday that went rather well, I was answering Jax top while my team won a 4v4 mid. Our Annie got a Quadrakill and I thought 'oh ok I can push this out then.' Jax disappeared. About 20 seconds after the quarda kill I suddenly heard PENTAKILL!!!!! which caught everyone by surprise.
So what is the formula they use for the pentakill timer? I've gotten would-be pentas closer together than that that just put me at 'unstoppable'
