So I snagged this the other day for 20 UC. Bonded it with the same choice and used the event to upgrade to level two. However, as you can see up the top I have these gold Starforge Stones and Star Fragments but unsure how they're able to be used? There's no option inside the Workshop area, and when I locate each one in my inventory and click "use", I'm just taken to the same screen as shared.
This is my first X-Suit and as you can see a little confused.
With some of these materials having expiry dates, I don't want them to end up unused and wasted.
Any help or clarification would be massively appreciated.
