But I already have his moveset ideas, though using the stone does make some of his Secret Arts easier to figure out...fine, you win. Now answer the original question and give me ideas.

Dragon Slayer Secret Art:

Feral Gaia: Jade Maelstrom- The user creates numerous jade stones fragments and then whips his arms around, creating a powerful vortex of jade stones that lifts its target into the air, leaving them defenseless with sharp shards of jade flying at them to turn them into mince meat. 

Feral Gaia: Jade Mallet- The user claps its hands together and creates a giant hammer made of jade and swings it down at its target with the force to substantially obliterate its environment. 

I pulled these straight out of the air. xD
