Guild Wars 2

I just crafted this back item, and got it to “stage 2”. There’s an upgrade slot there, but everything I tried putting there just turned it red (meaning it could not be upgraded).

I tried various things that were accepted as upgrades by other trinkets I have, nothing seems to work.

I tried major and superior sigils; runes; medallions and the jewel you get by completing PS. Nothing worked. What am I missing here?

Level 40 or lower jewel.

Keep in mind that at Stage 2 (2 blades), the Spinal Blades are a level 40 item. You can only put upgrades with a level 40 or lower requirement on them, and only of certain types (Jewels should work, though not raw gem pieces, as well as Marks and Talismans (Medallions are too high a level)).

Edit: Raw gemstones do, in fact, work (though the equivalent jewel will get you more stats, so you shouldn’t generally use them on a backpiece).

Thanks for clearing that up! The medallions were lvl 67 iirc
