Scorch Cannon

The Scorch Cannon is a Fallen relic weapon found throughout the Destiny series. The Scorch Cannon acts as a Solar-damage rocket launcher. Holding down the trigger converts the rockets into delayed explosion projectiles that stick to surfaces, these become more powerful the longer the trigger is held.

An unprimed explosion will kill most weaker enemies in usual content. A fully primed bomb will kill a shielded Major, but not an Ultra. The bombs will stick to both surfaces and enemies. In Rise of Iron, the Scorch Cannon made a return with new variants, the Shock Cannon and Null Cannon.

Grimoire Description
Scorch Cannons are shoulder-mounted heavy impact weapons used by the Fallen for hull-puncturing in ship-to-ship raiding parties.

''The Scorch Cannon uses a compressed Solar "furnace" to focus and direct superheated rods of solar energy. Each burst is mapped to the Cannon's firing matrix, allowing the wielder to hold a fired rod's charge. Release of the firing actuator triggers detonation. The longer the actuator is held the greater the rod's explosive impact.''
