Question about leveling up items

Relatively new to the game, but very much enjoying it, as I’ve played similar.

I had a question about Legendary Items - is it possible to level them up to a more advanced level, and if so, will the DPS/armor increase to the appropriate level as well?

For example, playing as the Rogue, I found the Thunderbluss pistol fairly early and it’s at level 14. I was wondering, since my character is now much higher than that, is there a way to level up this legendary pistol to match where my character is? Basically, keep my favorite items and enhance/evolve them to keep them relevant?

You can, but it will take quite a few medium-level crystals. I wouldn’t bother. You will find it again higher up.

Good to know, thanks for the reply!
