Would you find it worth while if they raised to to say 1000 or 1500 gems but gave it unlimited uses.
Yes.
That said, just before HoT I was able to use it to extract a poly luminescent undulating refractor (black) from something, and it didn’t become account or soul-bound…
Do I understand rightly that it’s been changed now, retroactively, on the upgrade extractors that I bought on the gemstore?
