Can i please get alistar

Go to Riot Support and submit a ticket asking for Alistar. I don't think the actual social media promo works anymore, but there is an automatic bot that gift him to you automatically. Bonus points: ask for the Unchained Alistar skin and you'll get that too.

you can't just ask for a free champion m8, you gotta buy with ip or rp

Isnt Ali like 450 ip? Just play like 3 games of aram
