Pc on some mods

Hey, in the Weapon Mod and Ins, i cant find mods like;

20/20

15^50

+30hp

Enchantments last 20% longer


So what is the price on those mods ?

Thx in advance ;D

Umm exactly for what weapon are the mods?

None atm. Cause i had them on some weapons, and one of u guys told me to salvage it.
