Smokebats may also be "baked in" to a piece of kindling, something between a Duraflame log and one of those firework snakes, which will spawn 20 rounds worth of smokebats when lit. This magic effect may also be put into a wand or staff, triggered when the end of the utensil is held to fire of any kind (without consuming the item). Some high level casters can bind this enchantment to their clothing or as a ward on their person, as a defense against fire attacks.
A spellcaster may expend a use of Fireball to summon 12d6 swarms of smokebats, or 6d6 swarms which will not attack the spellcaster.
Smokebats are only ever dormant or dying. If encountered alone, they function like normal bats except they're harder to see or hear yet easier to smell. They can only survive for long in the wild as breath vampires, and will try to cover their target's face and suffocate them if afforded an opportunity (like during sleep), drawing oxygen from their lungs and using the drowning rules.
