"An individual ayperobo is practically harmless, and often eaten by larger devils as a delicacy. Recognizing their weakness, ayperobos gather together and create colonies that communicate using telepathy. These swarms are much stronger, capable of holding their own even against some of the greater devils." -CoA pg. 238
Please share your stories of the Burrow action! Would love to hear how it turned out.
** Remember for this encounter, any giant insect in Malbolge deals acid damage instead of posion. Check out their attack buff too on page 140 of the module!
