A remix version of "RISE" featuring Bobby from IKON was also released shortly after, with the song being performed on the tournament's finals by all the involved music groups and artists.

The victory of China's Invictus Gaming over Europe's Fnatic in the tournament's finals marked the first time in League of Legends history that the LPL (China) as a region won the world championship, as well as the first time a non-LCK (Korean) team has won after five consecutive years of prior Korean winners.

[13][14] Although the South Korea (LCK) representative, Kingzone DragonX, lost to China's (LPL) representative Royal Never Give Up (LPL) in 2018 Mid-Season Invitational (MSI) Finals, all three teams from South Korea (LCK) started in the Main Group Stage, having won the 2017 Mid-Season Invitational and the previous two World Championships.

With the results of 2018 MSI and following their separation from the rest of the Southeast Asian (SEA) region, Vietnam (VCS) had a direct seed into the Main Group Stage for the summer split victor in their region, but unlike the previous year, Vietnam had no additional slots in the Play-In Stage for their summer runner-up team, because of the 24 team limit.

The North American (NA LCS) summer split champion team was seeded to Pool 2 due to their performance at the 2018 Mid-Season Invitational.
