Gravels[]

Gravels are special items you sometimes receive from winning Historical Campaigns or Last Man Standing challenges and perhaps some events.

Gravel

There are two uses for Gravels: merging specialties and creating Hades Stones.

Merging Specialties[]

Certain abilities can be merged by using Gravels. Each ability has to be at least level 3. For example, Hero's Valor and Blood Battle can be merged if you have those two Gravels in your inventory.

To merge Gravels, simply go to the Mystery Shop --> Item Exchange and click on the desired skill. Certain skills act as Base Gravels meaning you won't see the possibility of merging unless you pick Hero's Valor.

Once you merge the two Gravels they will become an item called a Chaos Stone. In this instance, it will be called "Chaos Stone of Hero's Valor and Blood Battle". You will need a Muddy Stone to turn that Chaos Stone into a Flysch.

Flysch

Muddy Stones can be obtained primarily from abandoning Insights in the Academy.

Bear with me now... once you have the Flysch, your Hero will need 400 Insight Points in the Academy. Once that is achieved, you will need to click on the Insight, then on the Merge tab and select the Flysch. Doing so will merge the two skills and free up one spot for another skill.

For a *not close to complete* list of mergeable abilities scroll down the page.

Hades Stones[]

Hades Stones are basically super powered Flysch's. If you have two Gravels of the same type you don't want, you can exchange them for 2 Freeze Springs in the Item Exchange. Once you have 30 Freeze Springs you can exchange those for a Hades Stone.

Hades Stone

Hades Stones will let you merge any level 3 or above specialties with almost no restriction. The one restriction being merging two exceptional skills, i.e. - Unrelenting Blows, Stunning Might, Supreme Fear etc.
