Editing LeviathanTempest:ChapterFive (section)

===== Sidebar: Swarms =====

Some of the creatures in this section are Swarms. In play a Swarm is treated as one individual creature. A Swarm's Size represents how many creatures are present and functions normally with the rules for exceptional size in combat. Swarms do not have health, instead damage reduces their Size: one point of Size is equal to two Bashing, one Lethal or half a point of Aggravated damage. To represent the combined effectiveness of what may be thousands of creatures Swarms may use the Exceptional Size rules as normal. 

Swarms also have double defence against most attacks. If the Swarm makes a Dodge action triple their unmodified Defence, do not double their doubled Defence. However against bombs, flamethrowers or other weapons that do damage in a wide area Swarms have no Defence at all.
