Swarm
PAP/MAP Cost: 2/0 Prerequisites: 3 sizes smaller than target

Swarm is like a charge int that the user(s) rush the target and attack. The difference is that the attackers enter the same space as the target, bobbing and weaving as a group making it difficult for the target to strike a single member of the swarm, even if the swarm has only one attacker in it.
Swarm does not protect vs area affects, auras, breath weapons or, burst type of attacks.

Target must roll before they can try an attack. The roll is 5 + Users Agility + 2 per size difference + 1 per swarm member vs Targets Focus + Awareness + 1d20.
Succeed in the roll to attack a swarm member, otherwise you are flailing about.

A target inside a swarm can chose to out run it.
