They're like Influence Points except they can only be purchased with real money. You can only unlock skins and other things by using Riot Points. It's basically how people can spend so much money on LoL even though it's "free".
Yaah, until then just studying the fuck out of this annie guide (shotgun her ftr) Oh ok, well that crushed many of my LoL dreams
Funniest thing was they gave everyone 350RP for free one time but it turns out the only things you can buy for that much are the xp/IP boosts.
I'm in a co-op mode atm with other noobs. Deadset me and my guy smash through our flank attract 4 champions and the other guys are going nowhere. On beginner aswell.
