How to Earn Influence Points
Influence Points are used to purchase many items from the Riot Store. While there's no easy way to earn them, they are accumulated as you play, regardless of whether you win or lose. Obviously the best way to earn Influence Points is to win, and in as quick a time as possible.
You will want to make sure you get the first win of the day bonus as often as you can, this will give you a significant lift. You could also buy an IP Boost using Riot Points. Bear in mind that playing PvP rather than against Bots will always give you more IP also.
