Shaping Shaping's a lot like scribbling, except that shapers make things instead of drawing them.

Where most talented folks have to work on the spot, shapers can jar up talent for when it's needed. When you see someone put their hands over their heads, it don't always mean they're whipped.
Signers pull their talent right out of the air, digging it along with fast movements of their hands.
Some signers use their talent to form conjurations. Others batter their challengers head on. Signing is always a tough one to face down.
