Enhancement Cores should be used to enhance a weapon / or perk. - not INFUSE. if you have Handcannon targeting on your helmet? and you want ENHANCED handcannon targeting? guess what... use a Core. infuse with Materials, and Masterwork with usage!- Get X amount of Kills with this Weapon to Masterwork it. you want a re roll on your stat / perk - you can do that as well! with an enhancement core! enhancing the weapon that you love! EDIT: OK so this has me thinking, the average cost of infusion + Masterworking is what = Round about 13 - 15 Cores? Hear me out. on average; You have 4 Perk Trees and 1 Stat. Sights + Mag + Perk 1 + Perk 2 and the Stat. Activate a Re Roll on a Tree / Stat (Randomized) = 1 Core. Activate a Re Roll on a Tree / Stat (Elimination) = 2 Cores. Activate a Re Roll on a Tree / Stat (Specific) = 3 Cores. so Inevitably, you can have the Roll you want 3 Cores x 5 Rolls = 15 Cores I would invest in this.
