While all snake swarms are dangerous, swarms made up of venomous snakes are typically the most lethal. Snake swarms of both types can generally be encountered in the same regions, dwelling in ruins or wilderness alike.
Venomous snakes slither and crawl over each other in a furious mass, their poison-dripping fangs glinting in the light.
