So some irl friends decided to goof around on the upcoming Clash event, and I can invite 4/5 of the people we need. The 5th has his ranked games played and is around the same rank as a few of the others/also his account confirmed for clash with the sms. Any help?
Hmm, not sure, does he have a Clash ticket? Also look at this older post: https://boards.na.leagueoflegends.com/en/c/bug-report/VxfyGov6-cant-invite-friends-to-clash
"I think they have to be online because i can only invite them online."
If this trick doesnt make it, I suggest you contact Player Support. Be patient, be precise. https://support-leagueoflegends.riotgames.com/hc/en-us/requests/new
I'm not read up on clash, is there maybe a honor requirement he doesnt have? Like be atleast h2 or something.
