Hello, how do you define a swarm? Comparing it to D&D mechanics or common sense.
We fought a swarm of Toot-toot-like creatures and there were about 24 of them. Each of us has 4 on our heads and each attacked with poison claws aka poison tipped toothpicks.
But this is not satisfactory, as a swarm has several properties than just x identical members each on his own turn.
One way would be to just consider the swarm a monstrous sized creature, perhaps with physical immunity of catch being spray attacks and aoes. But how would these two forms of attack work? nr of creature * shifts/creature?
How do you roll defense for each member? Supposed you have 1000 bees in a swarm and you fireball them. If the "creature" rolls over your attack, it takes NO stress? Each bee dodged it and lived?
A swarm is not that uncommon, especially in the Nevernever, where we will spend some time, chances of pixie swarms is high and we would like some sort of a system to have a fair combat instead of overwhelming odds against us.
