cool work! will you add the other civ ?
Aoe4 Combat Simulator
Add units on each side and press '>' to make them fight each other!
Hold Shift while adding a unit to add 5 of them.
Right click units on the field to remove.
For building, you can add garrison, emplacement and fortification by clicking the buttons on the unit, if applicable.
Hold Shift while changing garrison to add/remove 5 at a time.
Units do NOT hit each other at the same time, causing even the perfectly same matchup to end up with one side winning.
I have no idea the stat of Swivel Ballista, sorry!
Let me know if something is missing or wrong!
