Torsion Engines is a very helpful upgrade that benefits almost all siege machines the player can build. The Mangonel line arguably gains the most out of Torsion Engines due to the expanded blast radius remedying the unit's inherent lack of precision and making missed shots slightly more forgiving. Attack ground commands become more effective as more enemy units can be caught in the blasts, allowing tactical players to wipe out large contingents of cavalry, archers, scattered infantry, or even multiple siege machines with a single shot. Bombard Cannons also appreciate Torsion Engines and make an excellent siege and archer counter once it is researched.
Torsion Engines also affects some Castle units (Organ Guns, which inherently do not have a damage radius, Petards, and Ballista Elephants). Untrainable units that go in affected branches such as Flamethrowers, Jean Bureau, and Jean de Lorrain also get the damage radius increase by researching Torsion Engines, but God's Own Sling and Bad Neighbor do not because as Trebuchets they are unaffected.
Team bonuses Edit
A Torsion Siege Engine is a type of artillery that utilizes torsion to launch projectiles. They were initially developed by the ancient Greeks, specifically Philip II of Macedon and Alexander the Great, and used through the Middle Ages until the development of gunpowder artillery in the 14th century proved them obsolete, essentially all non-battering ram/siege tower siege units utilize torsion. It should also be noted that increasing the blast range is inaccurate, as torsions allowed their users to fire and reload faster.
