If we aren't going to have the option to buy materials from a vendor at the tower because it might hinder the whole "grind" experience, why not give us material booster consumables? It would work like ether seeds, black wax, etc. but instead of extra glimmer for killing certain enemies, when activated, every time you pick up a material instead of picking up 1-2 it would boost to 3-4. Each material type could have their own designated consumable, ie. one for spinmetal, helium, bloom, and relics. This is just an idea, what do you guys think?
