Is there a complete list anywhere of every item that has come from the alcove alchemy. Including those that may be retired?

None of the alchemy combinations have been retired as far as I know. Here is a SubetaLodge list of items you can create there. I'm not sure if there is an on-site list.

alright thx u very much

There was a thread in the old forums. It seems it was not migrated to the new forums, although it is still mentioned here.
