Swarmhive
Designers Note
A swarmhive is a plant creature that has become
the host to a massive swarm of smaller creatures.
The swarm has incorporated itself into the host’s
body and and has now effectively merged with it into
a single creature.
Creating a Swarmhive
possessed by the base swarm. The swarm aura
cannot be dispersed while the swarmhive is alive
but automatically disperses upon the death of the
swarmhive. The radius of the aura is determined
by the size of the base creature.
“Swarmhive” is an acquired template that can be
applied to any corporeal plant creature of size Small
or larger, called the base creature, and any swarm,
called the base swarm. The creatures of the base
swarm must be at least two size categories smaller
than the base creature.
Size

the same as the CR of the base creature or the base
swarm then increase the new CR by 1.

or special attacks possessed by the swarm. The
