I'm creating a Troop of casters and wanted to know if they could both deal their "swarm damage" and cast a spell in the same turn.
It makes sense to me since an attack for a swarm reads as follows:
creatures with the swarm subtype don’t make standard melee attacks. Instead, they deal automatic damage to any creature whose space they occupy at the end of their move, with no attack roll needed.
This means they don't spend their Standard Action to deal damage, it just happens because some of the creatures in the swarm are biting/hitting the target. That leaves other creatures available to do other things.
Am I missing some ruling against this?
