Let’s come up with new “war machines.”

I've come up with a new combat unit. Specifically, the Great Bombard. The idea is this: it's a very sturdy unit with high firepower. It attacks an area, dealing damage to its own units as well. It destroys city walls and towers. Creatures that occupy a single cell (I don't like to write "small creatures" because it can be compared to dwarves, and also "unicellular" because it's associated with a type of protozoa) receive one and a half times more damage.

Characteristics:

Attack: 30
Defense: 40
Damage: 50-50 (for each unit of "Attack" and "Magic" +10 damage)
Hit Points: 2500
Speed: 0
Initiative: 7
Shots: 15

Abilities: Destruction of castle walls. Area attack. Large projectile.

Price: 15000.
