Guild Wars 2

Has anyone figured out what to stick in the Fractal Weapon (Upgrade Slot)? I just received a Fractal Trident and I am not sure what upgrades can be used on it.

What do you mean (Upgrade Slot)? Is that how it’s actually named, or do you just mean that it has an upgrade slot (for a gem, sigil etc.)?

It has an (Unused Upgrade Slot) under the main damage stats. I tried sticking a gem in it and it wouldn’t work.

how about a sigil? XD its a WEAPON – it uses sigil, how hard is that to figure out?

why even upgrade it? it has no stats so probably meant for transmutation
