Rat Snake Swarm

Creature 2 — animal, swarm

SnareLANDAQUATICVERTICALanimalswarm

A solitary snake might be no cause for alarm, but a hissing mass of frenzied snakes can make even seasoned adventurers shudder. Rat snakes can reach lengths of up to 10 feet, and they gather en masse to hibernate as well as to breed. Though nonvenomous, these territorial snakes will strike anything that threatens them. Snakes of some variety thrive in every non-arctic ecosystem, each with their own particular hunting patterns and defense mechanisms.

Abilities

Swarm Mind — This monster doesn't have a single mind (typically because it's a swarm of smaller creatures), and is immune to mental effects that target only a specific number of creatures. It is still subject to mental effects that affect all creatures in an area.
Mass Wriggle
Swarming Strikes — Each enemy in the swarm's space takes 1d8 piercing damage (DC 17 Reflex save).

WORKS WELL WITH

AnvilLAND / AQUATIC / VERTICALA durable ally can wade into the swarm's space and absorb its area damage while others handle different threats.
SniperLAND / VERTICALA ranged attacker keeps dealing full damage where precision-reliant strikes underperform against the swarm's immunity.
FlankerLAND / AQUATIC / VERTICALA mobile skirmisher navigates the climbing and swimming terrain the swarm threatens, denying it free control of the space.

PUNISHES

✖ precision reliance✖ melee reliance✖ clumping
Avoid pairing with another space-denial swarm; overlapping zones of forced damage become hard for the party to route around.
