Augustina de Aragon's Cannon

Origin
Augustina de Aragon was present at the siege of Zaragoza by Napoleonic forces in Spain. She was delivering food to the cannon gunners when the French overtook them. Their line of defense was breached and many ran away to avoid gunfire. Augustina quickly loaded and lit a cannon, which shot itself into a wave of soldiers. Her sole manning of the cannons led the Spanish to return to their posts and help her fend off the attackers. They defeated the French, but they returned several weeks later and high casualties forced the general to surrender the town.

Effects
The cannon will not fire ammunition but instead release a powerful blast radius. All enemy combatants caught in the wave will be rendered immediately comatose or petrified, making them unable to move. The cannon will also apply the same affect to an equal number of the user’s group.
