seasonal helm weapons upon Lightfall release

[iron compass]

Im wondering if the seasonal weapons from the vendors in the helm will still be able to be crafted when lightfall drops if i have unlocked the pattern?

yes

We haven't had this situation yet, since crafting came with Witchqueen, but they wouldn't take patterns away for no reason, and haven't said anything about it so its safe to assume everything will still be craftable.
