[quote]Kinetic Rupture does not reliably stun unstoppable champions.[/quote] Don't use it, use bow mod or opening salvo weapon mod (etch on overload/barrier weapons given by artifact mod, you can have it be both on one gun, same for Killshot) If you don't wanna use Riposte for sword then use Opening Salvo instead, it's better Bungie intentionally made bad artifact mods and made the better unstop champ mod a weapon mod, it can be put on any legendary gun/sword/glaive so
