Hey! 
That means You're a returning player. As far as I remember those are parts of Misery gear. You have to upgrade your gear using golden talents and they will be converted to something else.
For that, open up inventory with any button you set and look for the new icon at the very bottom (that is not enchanting!). Insert your gear there and convert it. Once it's done, right click the enigmatic gear, set the rolls you need and it's ready to use.
Good luck!
PS.: While you're at it, use the promo code "brawler" for free stuff. 
yep, should be the upgrade button
it will also show you what materials you need to upgrade your gear in the future
just like the enchanting button 
May you post a screenshot of your gear please.
edit: just noticed your weapon was +10. I don't think you can convert misery if its not +12. Have you tried with your robe, gloves & boots?
It's just no longer possible to upgrade Guile pieces. It's a ninja change with last patch they couldn't be bothered to tell us about, unless it's a bug.
So, the answer to the main question should be to get the free Guardian set from the NPC in Highwatch, enchant it to +6, then upgrade it to Twistshard, enchant it to +9, then upgrade it to Frostmetal, enchant it to +0, then upgrade it to Stormcry, enchant it to +8 if you can afford it.
Have fun! o/

Guile was never upgrade-able to begin with, so no "ninja change". Misery needed (and still do) to be +12 in order to upgrade to +0 Twistshard.
After actually reading what gear OP has (I read what Glacial said, and just read "Misery", so I assumed it was Misery), it seems that he's wearing full Guile armors parts, which are not upgrade-able and a +10 Misery weapon, which is also not upgrade-able.
So yeah follow Sunflare instructions.

Totally forgot there was the Misery set! wtf

Guile was Tier 10 as far as I remember, and you could only upgrade Tier 11 or higher (maybe I am wrong).
And welcome back Karurosu
