In Monster Hunter World (MHW), stamina management is crucial for Dual Blade users. The best stamina skill for Dual Blades is Marathon Runner, which reduces stamina depletion by 20%. This allows Dual Blade users to attack more aggressively and dodge more frequently without worrying about running out of stamina.
Marathon Runner is especially important for Dual Blades because they are a very mobile weapon. Dual Blade users need to be able to dodge and reposition themselves quickly to avoid attacks and maximize their damage output. Marathon Runner helps them do this by allowing them to conserve their stamina.
