The only way to become a Gearmaster is through combat, constant combat! You must go challenge powerful monsters to experience the energy of the earth in combat.
Go to the Twin Lion Mountain and challenge a Sharkman Defender, Sharkman Fighter, and Sharkman Priest from the Sharkmen's Tribal Village in the southeast.
After that's done, go to the Schilling Village on the Prism Island Prairie and look for Sage Babama. He is waiting for you there.
Only he can break through your energy block and let you advance to a Gearmaster.
Child, I believe you are ready to let yourself become an outstanding Gearmaster.
The road ahead will be difficult, but I have faith that you will prevail.
