Okay. back in the old days, when you actually completed a shroud run and got on the timer, you used to always get at least one Large Ingredient per run in one of the end chests.

This is apparently no longer true. I know this because I just completed a Shroud and did not get a Large Anything.

I got a Shard of Supreme Power, which I vendored, because I have 10 of them banked and nobody else on the run wanted it.

Another shard of Supreme Power got left in the chest.

Then I claim my much-touted new end reward for the first time, and I get my choice of three identical Small Gnawed Bones, a couple pieces of Medium garbage, and another Shard of Supreme Power.

Apparently, the requirement of NINE LARGE INGREDIENTS to ONE SHARD is a ratio that is too complicated for the Developers to grasp, and until it's fixed, Shrouds are no longer worth running at all. The old vendor-trash weapons were better, because at least you got more plat from the vendors than for these useless shards.
