Ive done the whole quest line just didnt do it on legend. but i saw in videos that they can equip the catalyst did i do something wrong or is it just bugged i dont know what to do please help
Hey there. You earn a catalyst each time you complete the mission on Legendary. They are not linked to any quest, nor the Distribution Matrix intrinsic perk.
If you have not played on Legendary, then yes, you will not have any catalysts available.
