It being a budget weapon actually tips the choice in its favour as well since you can pick up multiple copies to briquette for +10% attack damage. For the price of 1 Karacha on Telsiai, you could Briquette and +10 a Superior Kracked Shooter come to think of it.
Karacha is also worse for Split Arrow because the bounce modifier is t0.
It is actually all things considered, pretty lackluster for your build, especially as refine rate goes up because the base damage increase is going to matter for the Split Arrow setup youāre going to do.
