Combustion

It was rarely used on a person, and the effects it had on inanimate objects and people were devastating. Depending on the size, density and vulnerability of the object in question, combustion would become harder or easier to use successfully. The intensity of the blast could injure an entire room of enemies, particularly if the affected object was made of flammable material.

It is disputed whether combustion could be prevented and stopped if another Force user concentrated on an object to prevent it from exploding. This may have canceled it out, or it may have done nothing. Yarael Poof was known to use this power.

Darth Sidious considered this ability a "mere child's play" in The Jedi Path: A Manual for Students of the Force. After his resurrection on Byss, Palpatine used this power to cause a 10,000 year old lightsaber to explode in Leia's hands.
