Catapults

A catapult is a simple device used in siege warfare. Used to hurl rocks great distances and over walls, making it a great option for fighting those refusing to take the battlefield. Though its cousin, the trebuchett, is objectively superior, one can get more creative with a catapult.

Weapons & Armament

The catapult itself is often compared to the trebuchett. Both are designed to hurl large rocks large distances and sail over fortifications. The trebuchett is objectively a superior siege weapon, capable of launching objects greater distances and in a higher arc, but the catapult is far more versatile.
As Raro the Lore Master notes, The Legion owes a great deal of its success to the catapult. During a particularly rough siege during their initial invasion, a fortified city (that has since lost its name) had closed its gates with its stocks over full. This city would have been able to withstand the siege for years. It was a particularly clever and cruel Legionnaire that decide to launch more than rocks into the city.
Disease riddle water, flaming barrels of pitch and excrement were launched behind the walls to promote disease and deprive them if sleep while corpses of the city's recently defeated army were launched to destroy their resolve.
When this tactic proved to be successful, the Legionnaire forced prisoners of war to collect communicable diseases and launched them, still living, screaming into the city.
The rampant disease and screaming proved to be too much to take and the city yielded.
A moor recent example of the catapults versatility was the first attack on Titan, where The Burned One had his men create catapults at the battlefield. Though the attack was unsuccessful, the catapults did extreme damage to the city.
