According to previously posted information, a member of a famous programming group on Facebook shared a tool for picking Yasuo or a pre-assigned champion in normal matches quickly. However, many people questioned whether Garena would ban accounts for using the tool.

In a discussion with us, a representative from Garena stated that currently using this tool will not result in account bans. This is indeed great news for the developer community as well as players on the Vietnamese server, allowing them to freely enjoy their favorite champions in normal games.

However, this decision may change in the future if violations of the League of Legends regulations regarding third-party software, as published on the homepage, are detected.
This situation is quite similar to the case of the modskin tool. In the past, Garena Vietnam initially announced that it allowed the use of it freely. However, due to excessive abuse, Garena took strict action against all accounts using the modskin tool.

Therefore, the best way is to avoid using the tool to prevent the risk of account bans on a fine day.
