From the Smoke Screen description on the Ash wiki page:

''Melee attacks hit for 50% extra damage while invisible (yellow numbers) and charge attacks for 100% extra damage, also these attacks can critically hit (red numbers). However, the Critical damage % mod (Organ Shatter) does not affect yellow hits, only red critical hits.''

If this information is correct, you want to focus on charge damage (Killing Blow mod) and Charge Speed (Reflex Coil mod). I've been also been noticing more red crits as of late while using Ash and the Dark Sword's charge attacks. I'll have to give DHS a try and see if I'm getting more on that weapon as well.
