Ettercap

The ettercap can climb difficult surfaces, including upside down on ceilings, without needing to make an ability check.

While in contact with a web, the ettercap knows the exact location of any other creature in contact with the same web.

The ettercap ignores movement restrictions caused by webbing.

The ettercap makes two attacks: one with its bite and one with its claws.
