Greeting SVI991, I'm sure you know this by now, but the item you're looking at is known as a "Gemstone". You'll need to refine it in order to receive "Jewel of Harmony" in which can be use to Strengthened Items. To make it easier for you, here are the steps: 1. Locate Lahap (Picture). Select "Dismantle Jewels" >>> unstack stone. 2. Move to The Refinery Tower ( KanturuCore level 320 ) >>>> Start heading to 78 174, and talk to Elpis. Picture 3. Select Refine Gemstone >>> The gemstone should start generating into a fresh Jewel of Harmony, however sometime it does fail. Once fail, the gemstone will be lost...and just cross your finger the next one won't be. 4. Adding Jewel of Harmony into your "Items" is the best part! There are many opt available for your item ( I would recommend "Damage decrease rate increase" for set). However,if you're unlucky and receive unwanted opt....it can be easily remove at Aida.
