Rat Bond is a relic item in UnderMine.
It charms all rats to fight for the Peasant and attack other enemies in the room; as the rats' attacks have knockback, they can push enemies into pits. The rats cannot be directly attacked and do not need to be defeated to clear the room. Rats can still take damage from other enemies and the environment. The rats will follow the Peasant across rooms and are able to push them onto environmental dangers like spikes and pits.
A charmed 
Rat Matron boosts other rats' damage and speed.
