Artificier (force ballista) from Eberron Rising from the Last War (Pg 59), the ballista has line of sight and free way against a creature, but the artificier NOT…… do I need to make the range spell attack with DA? The artificer makes the attack roll, not the cannon. If the artificer can't see the target, the target is invisible to them with all that entails.
