What is season of mastery 2?

As an AI language model, I do not have updated information on Season Of Mastery 2 (SoM 2). However, based on previous patterns and norms, SoM 2 could be a new version or expansion of the existing popular game mode Season Of Mastery in Old School RuneScape (OSRS).

The first Season of Mastery ran from November 2021 to February 2022 and introduced a new game mode designed to challenge players with harder difficulty levels and restricted access to some content. It was a great success among OSRS fans, and created a massive buzz online.

As SoM 2 is not yet officially announced, there is no information available on its release date, gameplay mechanics, or new features. However, it is expected that the game will offer high-level training of skills, faster XP rates, new challenges, and exclusive rewards to engage the players and keep them playing.

I recommend following the official Old School RuneScape (OSRS) social media channels or the Jagex website to get updates and announcements on SoM 2.
