The catalyst would be called "double down" What it does: >Takes the range, handling and stubility stats up to where the impact stat is >Doubles the fan fire perk from 4 to 8 >Headshot kills grants marksman dodge energy >Marksman dodge does not reset fan fire >Doubles the mag from 8 to 16 rounds >Aiming with this gun doubles its effective range (like pre nerf but with range finder added) >Landing shots while aiming does activate fan fire How to obtain it: Ether by winning crusible matches or using last word for 20% of your time played (once you obtain the catalyst you will need 2000 hip fire headshot kills in pvp to fully masterwork the last work)
