That last paragraph of my first comment is the method. If you have a large amount of legendary shards (2,000+) and are willing to potentially sacrifice up to a couple hundred, (last time I did this I spent 2500 and lost 350 of them - it's unfortunately a gamble where sometimes you can almost break even on what you spend and sometimes you lose out quite a bit) you can do this. Just wait for a day for Spider to sell Simulation Seeds for Legendary Shards. 1 Shard = 5 Seeds Take the seeds you buy to Brother Vance for his reputation packages. 60 Seeds = 1 Package One package generally gets you one of two potential drop combinations: 6 Shards 1 Legendary (Masterwork Potential) 1 Shader (Always Legendary, Recycles into 1 Shard) OR 1 Shard 2 Legendaries (Masterwork Potential for BOTH) 1 Shader (Same thing, always Legendary) You can also get legendary sparrows, ghost shells, and Exotics as supplementary drops. Doing the quick math, getting the one Legendary drop package gets more Shards back if you recycle all your shaders and dismantle all Legendary drops. However, that also means you get less Legendaries overall. Which means less Masterwork potentials.. so less cores.
