Thanks for responding.
Twin Arrow is fake multi hit. You will see it hit 2 time. but in fact it’s one hit 150% dmg.
full attribute = 150%*2
Running shot will give you attack speed 30%.
every lvl of running shot will give you +40% dmg.
lvl1=100+40%
lvl5=100+200%
lvl7=100+280%.
lvl10=100+400% (special setup req)
running shot have higher dmg. but need to stick with grand cross weapon.
twin arrow alone can’t compare to running shot. but if you compare multi-shot15+twin arrow with running shot it will be different story.
