The rare Halloween weapons and some other unobtainable weapons are now available via the Mystic Forge according to a developer on Reddit.
The old Halloween weapons such as Greatsaw Greatsword, Ghastly Grinning Shield etc are now obtainable as a random drop when you combine weapons in the Mystic Forge.
This was a part of a bigger update to the mystic forge which wasn’t quite ready for this patch, so we pulled most of the changes as well as the release notes. However, since this change did go into the build, I wanted to let everyone know about it.
