League of Legends players are preparing for the arrival of the new champion Lillia, who will arrive alongside the ‘masked assassin’, but Riot Games is warning players that Lillia will come with “steep learning curves” ahead of the arrival.

Both are expected to arrive on the Summoner’s Rift in Patch 10.14 which is due out later this week.

Lillia will be League of Legends 149th champion, while the “masked assassin” is rumored to be Yasuo’s brother Yone and will arrive alongside Lillia.

“Our upcoming dreamy jungler and masked assassin are both likely to appeal to players looking for more novel experiences, and will require a pretty heavy investment to get over the initial learning curve,” Riot Games stated (h/t Dexerto).

“While we’re confident that mastering these two new champions [expected to arrive together later this week] will be worth the effort, there will likely be some bonus ‘feels bad’ feels too, especially in comparison to simpler future champion releases.”

“We don’t want players to worry about us releasing new/updated champs that consistently dominate like they have in the recent past,” they said. The ability to take a longer-term approach should mitigate this, they added.

“Without a pressure to make these champs win at the same rate as the rest of the champion pool at release, we can better ensure they’re not running away with games as players become more experienced on them.”
