- Objects have various effects that can help you during battle. They cost GP to add to a formation, and each formation has limits the total GP you can spend on placing objects.
Also, some units and monsters have skills that let them place objects.
The human catapult is a unique object that lets you quickly launch your own unit behind enemy lines.
Aim your unit at the enemy's formation and fire! Attack from both sides and seize the advantage!
If your timing is off, though, that unit might end up isolated and surrounded by enemies!
