As a defensive castle Catapult, I was thinking like the Castle Archers, but instead of the following ideas.
It'd be more like a general shotgun going to more random spots hitting a larger area, but with less aim.
Or a catapult that would shoot, say three to six dead randomly out into the field of play to fight whatever is coming to attack you. But with the deads flying and then laying hard and then having to get up. I just think it'd be a cool visual and slow down any attack and give the defense more time.to prepare.
This could be the Chaos one, and an order one could be like a sneak attack of three to six sickle wrath coming out of a bush as a sneak attack, but it's for defense.
Probably mainly be used in Ambush defense
