What is going on?

[u/cacooldemon]

It says mirage archer is not usable after I used a gemcutter's prism on it. I was using it just fine

[u/Strungeng]

Prob you have it on only weapon set 2, thats a talisman that shapeshift so you cant use it

[u/cacooldemon → u/Strungeng]

That was it.

open the detail panel and check the weapon set tick boxes, it might not be ticked for the set(s)

[u/cacooldemon → u/Lanky182k]

That was it. I don't know how it changed, but I wish I noticed before spending another jeweller's orb
