Guild Wars 2

Can someone tell me what upgrade is used in a superior back piece like the new crafted ones? Nothing I am trying works, and I’m tired of spending gold to buy unuseable upgrades.

The new crafted back pieces are only level 78 (no idea why) so you can use any gemstone/seal upgrade that is below level 78. For example the Ruby Orb cannot be inserted as it’s level 80 but the Ruby Crystal can as it’s level 65 -

thank you! This is a pain.

Brilliant Jewels are the “best in slot” upgrade for the crafted backpieces. A bit better than the “raw” jewels that the above poster suggested.
