Dm Secret; Swarms are resistant to bludgeoning/piercing/slashing damage. And they tend to be small buckets of health that hit hard but have minimal bells and whistles. Tralaya are special and dangerous, but the big thing is ‘bucket of health that does a chunk of damage’ for Swarms.

For rules purposes the swarm is one ‘creature’. So go for it!
