A ballista is a massive crossbow that fires heavy bolts. Before it can be fired, it must be loaded and aimed. It takes one action to load the weapon, one action to aim it, and one action to fire it. The bolts it fires count as spell attacks by you dealing 3d10 force damage on a hit (Range 120/480).

The ballista is on wheels, on your turn, you can use your action and movement to push it 10ft.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the force damage increases by 1d10 for each slot level above 1st.
