Swarm

Creatures with the "#Swarm" Creature Tag can come together to form a Swarm. To form a Swarm, there needs to be 5 or more of the same creature within a Spitting Distance(4u) of one another. When this happens, the group can form together into a Swarm as a Free Action.

As a Swarm, the creatures are no longer tracked individually, but share a pool of Health and Vitality equal to the sum of all their Health and Vitality combined. A Swarm starts as a Huge(4u) Sphere Shape. For every 5 creatures in the Swarm after the first 5, the swarm grows one Size (covering a Massive(8u) Sphere at 10 creatures and Gargantuan(16u) at 15 creatures.) A Swarm can use any Abilities of its creatures to target any or all creatures within their Swarm area simultaneously. For every 5 creatures in the Swarm, they also gain an Advantage on any Tests for the Abilities they perform an on any Saves they must make. The Swarm loses its Advantage on Saves against Abilities that target an area fully encompassing the Swarm.
