Earthquake

Shatter, Earthquake and Purgatory are attack weaves that manipulate earth to
wound a foe. Purgatory is strongest, followed by Earthquake.

Because it requires so little One Power skill, Shatter is among the five
‘cantrips’ often used by channelers to improve their strength in the spheres
of the One Power (along with Burn for fire, Airclub for air, Flog for water,
and Cure Light for spirit).
