Someone tested the delve sword?
What categories it can be augmented?
Thanks in advance.
This isn't answering your question, but I believe the Mezzotinting paths are different for the new Delve items. I picked up this last night and noticed that the Magic Accuracy path is different than the original items. So that stands to reason that the swords and other items will also have different paths as well.
For Twebuliij, the following were options for upgrading with Airlixers:
Path A: MP, Magic Attack and INT
Path B: MP, Magic Accuracy and MND
Path C: DEX and something else, I don't remember, but it was more or less a melee/DD path for the staff.
