Ever since house of wolfs came out I've been trying to get keys for prison of elders, but i have a big problem with my special ammo synthesis it has filled my warlock and my titan and most of my vault and its starting to fill my hunter. I want to be able to delete synthesis its over whelming my characters and i don't even have room for the keys Ive been trying to get in the first place. So please bungie help me out and many other destiny fans delete unwanted amounts of synthesis.
