Recently used the services of KingBoost…

Recently used the services of KingBoost and I am truly blown away by the quality. My booster, Shadowbass, worked incredibly hard and put an immense amount of time and dedication into optimizing my character. The result exceeds all my expectations: the build is optimized down to the smallest detail and plays fantastically.

Communication with both the booster and customer support was extremely smooth, friendly, and professional. You can tell in everything they do that they know exactly what they're doing. This is definitely worth the money and I will certainly be coming back here in the future. Highly recommended!

Keystone Myth carry

I ordered a Keystone Myth carry with the guys. Once my order was placed, i was contacted on discord promptly by the service, and my designated carrier. My carrier was Diavolein. He conducted himself professionally and courteously in our conversation. He was flexible about when I could schedule my carry. We decided on a time, and he was ready by the scheduled time. The runs went smoothly. There was only one real wipe to speak of in Windrunner Spire, and a few erroneous deaths here and there (some of which were mine XD), but all dungeons were completed in good time. I had my 3.4k rating by dungeon 7, did not even need to run an 8th.
