Clarification on how extracting Aspects will work on Legacy Legendary's

Hey all, can someone clarify how extracting Aspects will work when Season 4 starts? I found the thread where Pez explained how it works if you have already extracted the aspect, but I can’t find an answer on whether the process will automatically extract the aspect if we have the actual item sitting in our stash or if we can still extract those aspects at the blacksmith from Legacy items.

Aspects are added to the codex when you salvage legendaries at the blacksmith.

Right, for new S4 items. Just want to clarify that also will apply to legacy items.

Yes, it will. You don’t need to extract them before S3 ends.

Perfect, thanks! Save time and gold haha.

Safer to extract before S4 as we dont have information whether the extract of legacy legendary will upgrade codex. It just cost you money to extract, so not worth to take risk.
