You can only have a max of 20 Ascendant Shards and 100 Enhancement prisms. The trick is once you have the max number. Pull out trash exotics from collections. Masterwork them and store them in your vaults for Beyond Light. When Beyond Light drops dismantle if needed to get Ascendant Shards and prisms. Goodluck mates and have fun farming this week's double loot lake of shadow. Btw what's your highest exotic stat drop you've gotten from lake of shadow? Mind so far is Lucky Raspberry with a 67 stat distribution. I seen a 71 sixth coyote from a friend.
