Quick Reference
Running This Encounter
Giant Rats are best used in groups of 3-5 to pose a meaningful threat to low-level parties. They swarm targets and use their Pack Tactics feature to gain advantage when multiple rats attack the same enemy. Describe them as diseased, aggressive vermin that screech and snap at adventurers. Use their small size to allow them to move through tight spaces and create tactical variety.
Combat Tactics
Giant Rats use Pack Tactics to gain advantage when attacking with allies nearby, making them more dangerous in groups. They target isolated or weakened party members and attempt to surround them. Rats prioritize attacking prone or restrained targets.
Environment & Setting
Giant Rats thrive in sewers, caves, underground ruins, and ship holds where filth accumulates. They nest in dark, damp areas with multiple escape routes and hiding spots.
