Wait what is this gear infusion and how do you do it?
Upgrades attk or defense of lower valued LEGENDARY gear by sacrificing higher valued gear. It's basically good for if you like certain gear and want to keep them but it's too low leveled for you to progress.
Infusion example
100 Legendary gear of any subclass
200 rare/legendary gear of any subclass
200 gear --- infusion ---> 100 gear
*explosion*
100 gear is now 200 gear
Original 200 gear is dismantled
Caveats:
Requires 1 mote of light
Weapon parts
Glimmer
And 3 marks
Weapon must be legendary to increase
Increased Weapon does no always exactly reach the same attack
MUST occupy same slot. Meaning primary to primary, special to special, boots to boots. Doesn't matter the type of weapon (shotgun, sniper, etc.) doesn't matter subclass armor is for (hunter, Titan, etc.).
