S for Onslaught. Will help with other missions.

Got my S+. Will help others if you need another.

I just need a group to get S on Onslaught, but I can help with other missions if looking for a group.

Someone made a guide about getting an S+ so consider reading it if you are doing this as well. https://www.reddit.com/r/leagueoflegends/comments/6ytji7/star_guardian_onslaught_s_guide/
