Build Your Keystone



Build your keystone service is a unique service and its primary function is to help our clients even after our job is done. This service is pretty straightforward. Our professional mythic+ team will invite your character on a mythic plus adventure where they will only play on your own keystone. The goal is to upgrade your personal keystone to a mythic +10 level and complete it as well. Build Your Keystone service is amazing for both new and seasoned players for numerous different reasons but the most important one is that you get to keep a high-level keystone. Aside from having a high-level keystone which will help you clear higher mythic+ dungeons with random people, you will also get the maximum weekly chest reward on a reset day. Because our mythic plus team is highly equipped, you will also receive all of the gear dropped during our service that fit your character’s class and specialization. If you don’t have a keystone +2 or higher, our professional players will help you obtain it. Make sure to check our Mythic+ Dungeon product page if you are interested in completing higher Mythic+ keystones than level 10.

For our Mythic+ Dungeons boost we will take your character to any dungeon of your choosing and complete it on a mythic +2 or higher difficulty, so you can receive a maximum ilvl reward at the end of the run, but also in your class hall’s weekly chest. For this service you can either play alongside our team, or we can have a professional booster log onto your account and play for you.

If you’re interested in setting a time and date of your choosing you can always give us a notification in a note or say it directly to our support agents. However, if no indication has been made, we will begin as soon as possible, normally less than 60 minutes after the purchase has been made.

The delivery time of our Mythic+ Dungeons boost is usually around 30 minutes per dungeon after you received an invite to our team.

By purchasing the Mythic+ Dungeons boost from us you are in violation of Blizzard’s ToS, but due to the professionalism and discretion of our boosters not a single customer received a penalty or suspension for using our services.

By completing a mythic +2 or higher dungeon in time you will receive 3 or more items at least the end of the run with an item level of 345-365+. Our boosters will trade any items they receive to you. Also, at the end of the week (regular Wednesday reset), a weekly chest in your class will be waiting for you with a 355-375+ ilvl item.

Selfplay option is when you play on your account and together in a group with our professional boosters clear the World of Wacraft content you are interested in.

Account sharing is a standard procedure we use for almost all of our services. This implies that our professional booster will log into your account and play on it for the duration of our service.

The boosters we use are located all over the world, they are extremely skilled Fortnite players, fluent in English Language and most importantly they do not work for other companies besides us, which increases the overall safety of our services immensely.

In an event where we do not deliver what we promised, or if any harm befalls your account due to our own fault, we offer a full refund of your initial payment. For more information about refunds, you can always check our Refund Policy page.

No. We do not use any third party software, hacks, bots, or any kind of program that would give us an unfair advantage over other Fortnite players. All our boosts are 100% done by hand and through the skill of our players.
