Making progress in the new League of Legends event hasn't been easy, and this is due to the number of points that missions award, as well as how laborious it is to complete them. Riot Games has noticed that players are not progressing according to expectations, and has offered a solution.
Completing the Rise of the Sentinels event quickly is important in order to obtain the cosmetics, but due to the mechanics this has become somewhat impossible. For example, there are Olaf objectives that change depending on when you meet him in the game.
"We're adding a repeatable mission : Play a PvP [player vs. player] game on Summoner's Rift, Ultimate Spellbook, Teamfight Tactics (normal + ranked) to earn 600 progression points," shared Riot 84Slashes.
So now it's just a matter of waiting 24 hours to repeat missions and get more points.
The Rise of the Sentinels event will continue throughout Patch 11.15, which debuts with Akshan.
