Riot and TJ Sports launch a global event for LoL's second tier

The teams that play under the top leagues of League of Legends are getting an international tournament of their own. Riot Games announced it on Thursday, September 3, 2026, on its LoL Esports site: the 2026 World Star Challengers Invitational, or WSCI, brings together sixteen teams from the second tier of five regions, from September 20 to October 2.

The second tier, which Riot writes as Tier 2, is the layer of leagues under the main regional championships. It is where academy teams, the junior rosters of the big organizations, play alongside independent clubs, and where most professional careers start. Riot's post presents the new event as the first time teams of that level meet on a global stage, with every major region represented.

Riot's post calls the tournament a collaboration with TJ Sports, the company that organizes the LPL, China's championship, as well as the Asia Masters, according to Sheep Esports. It is described by Riot as a pilot: an edition meant to test what an international competition for this level could be.

LoL Esports announcement of September 3, 2026.

Sixteen teams, three per region and one champion

The field is built by arithmetic. Five regions take part: China, Korea, APAC, the name Riot uses for the rest of Asia and the Pacific, the Americas, and EMEA, which covers Europe, the Middle East and Africa. Each sends three teams. That makes fifteen. The sixteenth is the champion of the Asia Masters, an existing tournament of TJ Sports.

Riot's post does not name a single team. It says each region will use a mix of qualification pathways to choose its three, which leaves the method to the regions. It does not say which region the Asia Masters champion counts for.

Sheep Esports, in a report published the same day, gave the outline of the split. Korea's places go to teams of the LCK CL and China's to teams of the LDL, the second-tier leagues of the two countries. The Americas split their three between one team of the NACL, one of the LRN and LRS, and one of the Circuito Desafiante, the Brazilian league. APAC does the same with one team each from the PCS, the LJL and the VCS.

Groups of four, played twice over

The tournament has two stages, and they are built differently.

In the group stage, the sixteen teams are divided into four groups of four. Each team plays the three others of its group twice, a system called a double round robin. Every match is a best-of-one: a single game decides it.

The numbers follow. Four teams make six pairings; played twice, that is twelve matches per group and 48 for the four groups, the total Riot's post gives. They are spread over six match days at eight matches a day. Each team plays six times, and no team can be sent home by one bad afternoon: the standings are made over all six games.

The two best teams of each group go on. The other eight, half the field, are out on September 25.

How the draw keeps regions apart

Who meets whom in the groups is decided by a draw with rules. Riot's post sorts the sixteen teams into three seeding pools, which are baskets of teams ranked by strength. Each group receives one team from Pool 1, one from Pool 2 and two from Pool 3. With four groups, that puts four teams in each of the first two pools and eight in the third.

Two limits apply. A Pool 1 team and a Pool 2 team of the same region cannot be drawn into the same group. And no group can hold more than two teams of one region.

The effect follows from the second limit. A Korean or a Chinese team that has spent its year against the same domestic opponents will play at least two of its three group rivals from elsewhere. The post does not say how teams are assigned to pools.

Seven series to a champion

The bracket stage starts on September 27, after one day without matches. Eight teams remain and the format hardens: single elimination, where the loser of a series leaves the tournament.

"Every bracket-stage series will be best-of-five," the post says. A best-of-five is won by the first team to take three games, so a series lasts three to five games. There are seven of them: four quarterfinals, two semifinals and a final, played on October 2.

For the team that wins the event, that means three series after its six group games, or between nine and fifteen more games in six days.

Why Riot is doing it

Riot's post spends a full section on its reasons. It calls the second tier a key feature of the competitive pipeline of LoL Esports: the place where emerging players develop, where teams invest in future talent, and the bridge between amateur and professional play. The publisher writes that it wants to create more opportunities for developing players and their teams.

"International competition can play an important role in that development," the post says. Its argument is that facing unfamiliar opponents exposes a team to other styles and strategies, and gives players the experience of a higher-stakes setting before they reach the top level.

The choice of method is stated too. Rather than build a new tournament from nothing, Riot writes, it is working with TJ Sports to expand the Asia Masters and to bring teams from Korea, EMEA, China, APAC and the Americas into it.

What it adds for Europe's regional leagues

For EMEA, the WSCI is the third door opened to second-tier teams in 2026, going by Riot's own announcements.

The region's second tier is made of thirteen regional leagues, known as ERLs, according to the season outline Riot published on November 27, 2025. Their best teams meet three times a year at EMEA Masters, the continental tournament of that level.

The first door was at the top. Two ERL teams, Karmine Corp Blue, the champions of EMEA Masters Summer 2025, and Los Ratones, two-time EMEA Masters champions, were invited to LEC Versus, the tournament that opened the 2026 season of the LEC, the main European league. It was a best-of-one round robin against every LEC team, with a guarantee of at least eleven games each. The second came in March: Riot's primer for EMEA Masters Winter, dated February 26, gave the two best teams of that 36-team event a place in a qualifier for the Esports World Cup alongside the ten LEC teams.

The WSCI is different in kind. Those two openings put second-tier teams against their own region's first division. This one puts them against the second tier of the other regions, the kind of meeting Riot's post presents as a first.

The scale gives an idea of how narrow the door is. Riot's format explainer for 2025 counted 16 teams at EMEA Masters in winter, 32 in spring and 44 in summer, and the winter edition of 2026 grew to 36. The WSCI takes three teams from the whole region.

One question the announcement leaves open concerns academy teams. For the Esports World Cup qualifier, Riot's February primer set a rule: the academy teams of LEC organizations could play EMEA Masters but could not take the two places, which passed to the next best team that was not an academy. The WSCI post states no rule of that kind, in either direction.

A crowded autumn

The dates fall in a busy part of the year.

Riot's season outline of November 27, 2025, placed EMEA Masters Summer from September 21 to October 19, which would start it one day after the WSCI and run it through the whole event. The outline said the details of EMEA Masters would be announced in the new year. Sheep Esports reported on September 3 that some teams were concerned about what the overlap would mean for the start of EMEA Masters, and that it could not confirm whether the schedule would change.

The final on October 2 comes thirteen days before the World Championship, the first-tier event of the year, opens on October 15.

Several points are not in the announcement. Riot's post names no city and no venue, gives no prize pool and lists no team. On broadcasting, it says fans will be able to follow the tournament through the regional Tier 2 social channels, and that regional co-streamers, creators who rebroadcast matches with their own commentary, will carry it around the world.

The first matches are played seventeen days after the announcement, on September 20.
