i just found out about the [Phenmor] and well, it's got DA so it's gonna (hopefully) delete SP grineer and corrupt.

Perks:
RW because +20% fire rate is funny, but all of them are viable.
EF gives a chance for insta-reload, and with 5 fire rate and only 30 rounds, having that chance will help a decent amount. it is up to preference tho.
EE since we want as little crit chance as possible, also increases status to 90% if it's actually additive like it says in the wiki. if it isn't we get even more status.
DA to round up the build. why? because even though it's not guaranteed, 2000% is absolutely insane, and it being able to proc on 50% of non-crits? i like those odds.
let me break the chances down for you:
45% chance for non-crit without DA which will around 15k
10% chance for crit which will deal around 30k
45% chance for non-crit with DA which will deal 300k
all of this before other perks and without galv aptitude, mainly because it doesn't work normally on incarnon, becoming multiplicative but not showing those dmg numbers on overframe.

remember that you have a fire rate of 21+ and over 400 rounds in incarnon mode, this shi gonna melt SP enemies.
pls give feedback i need to know if the build is actually viable
