This weapon is strong and maybe stupid with this build.
1st case : You are facing a huge pack of ennemies ; kill them all with secondary fire and double jump during the reload for [Motus Setup]. (And you won't deal any damage during this moment anyway)
2nd case : You are facing weak split ennemies ; kill them one by one with your primary fire and double jump during the reload.
3rd and final case : You are facing strong ennemies ; use your secondary fire at least once for viral proc and then, kill them with your primary fire.
PS : DOUBLE JUMP DURING RELOAD ! :'D
