Ohh a year 2 noob that is confused ok it will fill you in. In year one vault of glass Used to drop 300 attack weapons and you would get acendant materials during dismantle or from chests Croats end same principle but instead it gave out radiant materials and weapons at 331 attack Prison of elders scrapped the whole material stuff for etheric light (which can be traded to Petra for 500 faction rep) the weapons dropped at 365 attack When the taken king came out those raids got left behind and all the stats went into a star crunch making the year one gear 170 max and unless they bring forward the old raids they will always be 170. Making them useless for rewards. Acendant or radiant materials can be given to the speaker for motes or glimmer.
