Okay. So. I know most people don't think of [Sarpa] as a good weapon. But it is, if you use it right. It is one of two gunblades that can use [Shattering Impact], and the only melee that can remove 60 armor in less than a second using it. I've been using this build for a while now, and with its status chance being so high, [Condition Overload] gets this thing to nearly 50k damage on a critted heavy attack. That's with no combo beyond that given by [Corrupt Charge], and with windup accelerated by [Killing Blow]. So it deals approximately 420% (hilarious, I know) of the base heavy attack bullet damage with the first shot. If that inflicts a status, which is fairly likely, the damage of the second bullet increases to 924% of said base heavy attack damage.
What I'm saying is that this thing is a self-condition-priming beast of a weapon, and that people should try it out.
