Magic Mosquitoes?

[armorwars1]

Greetings

Of all the various spells in the pathfinder rules that summon/create swarms of creatures (rats,bats,spiders,centipedes,locusts ...etc).
Whips of... plagues and dooms. How does swarm damage interact with damage reduction? Are any of the swarms created/summoned by these magics considered magic?

[Fuzzy-Wuzzy]

The swarm isn't considered magic just because it was brought there by magic, no. Some swarms may be magic in their own right, but not in general. They interact with DR normally.

A swarm's attacks are nonmagical, unless the swarm's description states otherwise. Damage reduction sufficient to reduce a swarm attack's damage to 0, being incorporeal, or other special abilities usually give a creature immunity (or at least resistance) to damage from a swarm. Some swarms also have acid, blood drain, poison, or other special attacks in addition to normal damage.

So, if the swarm does 2d6 plus poison, the GM rolls 7, and you have DR 5/magic, you only take 2 damage (plus the poison) unless it's an explicitly magical swarm attack. If the GM rolls 5, you take no damage and are not poisoned.

In a specific way yes as the summoning spell, let us say, keeps the critter there and is subject to supression(antimagic field) or dispelling. The creature summoned may not be magical in nature.
