The popular Yomasu Patcher (also known as Yoma Soou ML Injector) is one of the most popular mods for Mobile Legends: Bang Bang (MLBB).
This ML injector or mod APK allows players to use most of the skins in MLBB without having to purchase any of it.
However, only the player who installed this mod can see these skins. Other players will only see the default skin of the hero.
While the MLBB Yomasu Patcher doesn't ruin competitive matches, players using it are still at risk of being banned from the game.
According to Moonton's in-game rules, players who use any kind of injector or modified version of MLBB will be severly punished.
Some modified apps and ML injectors also might contain virus or any kind of malicious software that can either break your phone or make it too slow for playing games.
Therefore, it is not advisable to use the Yoma Soou ML Injector or any kind of app that will modify MLBB or players will risk being banned permanently.
