Purification is a protoss war technique used to destroy all life on planetary surfaces, usually to eradicate the presence of zerg.

A purification attack consists of ships firing massive energy beams at a planetary surface, sterilizing it. Carriers can carry out the technique, firing energy from their tips as can motherships and possibly other large ships.

The process is powerful of burning holes in a planet's crust deep enough to allow magma to escape to the surface, along with dispersing (some of) its atmosphere. Minerals on purified worlds are often altered by the attack.

History
When the protoss discovered the extent of the zerg infestation of Chau Sara, Executor Tassadar reluctantly ordered his expedition's ships to power up their weapons, destroying the planet, firing at both terran settlements and other points. At least two ships, firing massive energy beams, obliterated most or all life. A small number of marines, including Andre Madrid, survived the attack by hiding underground.

Tassadar avoided attacking the next infected world, Mar Sara, until after the terrans had evacuated. Several hours after the escape, Tassadar's forces again sterilized a planet.

A large war between the zerg, Terran Confederacy and Sons of Korhal broke out on Antiga Prime. After a particularly devastating zerg attack on the Confederacy (guided by a psi emitter), Tassadar's forces attacked Antiga Prime, purifying it.

Tassadar's fleet arrived at the Confederate capital world of Tarsonis, which had been besieged by zerg due to the Sons of Korhal's use of psi emitters. Sarah Kerrigan, a ghost, believed that the Protoss Expeditionary Force arrived with the intention of destroying the planet. Forces under her command defeated the protoss. The protoss did not purify Tarsonis. Protoss, zerg and terran forces continued to fight on the planet's surface.

Following the Brood War
An attack took place under mysterious circumstances on the ice world of Braxis sometime after the Brood War. The planet "refroze" since the incident.

The protoss also partially purified the world of Urona Sigma in 2502.
