UNSTABLE BOMBER | 3 MILLION DAMAGE PER MAGAZINE | ONCE HUMAN
bombarider souvenier based build
most damage comes from weapon damage, explosion are mostly for procs, so this works well even in fights with status damage immunity as even if explosion deals no damage it still gives all procs
You need to have 20 or more bullets for this to work, for precision style calibration you will need extra 62.5% magazine size cap from all sources
