Bending the elements…
Throw a floating earth projectile with magma support.
EarthShot pulls an earth block into the air as a floating projectile and launches it in the direction the caster is looking. The projectile can be steered slightly while flying, and lavabenders can convert it to magma by holding sneak while looking at it, doubling its damage.
Tap sneak to raise the source to eye level, then left-click to throw. Hold sneak while looking at the raised source to convert to magma.
