How important are Primed Target Cracker and Primed Pistol Gambit

[Gravitas2]

So I am missing those two mods and I want to build the vaykor marelok and lex prime. Are those two mods essential or can I use the non-prime versions?

Unless you're planning on going above lvl 100 enemies, there's no need to worry.

If you're still thinking of using them in the future, get a head start on formaing the proper polarities.

They are worth it, but if you can't grab them from Baro when he drops them again, there is nothing wrong with using the non-primed versions. (It takes 512 rare 5 cores approximately to fully rank a Primed mod, so it is a bit more cost efficient to use the normal ones.)

You won't lose in the long run though even if you don't have them, there are ways around not doing as much damage as someone else. :) Like Crowd Control for instance :D
