Make mist breathing specialise in obstructing sight for the opponents, since canonically this is true, and it adds a new playstyle to the game.
example: Mist breathing skills create clouds of mist around the user everytime an opponent is hit by them. The more hits are landed, the larger the mist cloud gets. The clouds restrict the opponent’s vision, but the user can easily see through the mist. The user’s movement and attack speed are increased inside the mist. The user also becomes translucent and difficult to
spot. Mist users cannot be highlighted not revealed when inside mist (ahem arrow bda). Opponents move slower in mist by around 20%. Opponents’ screens will be a bit blurry once they exit the mist, and will stay blurry for 3 seconds. Mist lasts for 5 seconds.
each time this passive is activated, the amount of mist released isn’t much, so skills that involve multiple attacks (e.g. dsrpg2’s mist second skill) will be more useful.
to counter this, opponents have to keep a safe distance so they don’t get caught inside the mist, and make sure the mist user doesn’t use any skills near them. alternatively, opponents can use i-frames to run out of mist clouds.
note: being in mist clouds should also remove the team marker for mist users in hvd
