It's a creeper, an ambush predator, so probably not much chop in a stand-up fight. It's the sort of thing that would sneak up on stragglers in the dark and gobble them down without, hopefully, alerting anybody too dangerous.
It has a venomous sting on the end of its tail. I guess it would probably use that to silence and immobilize its prey before beginning the swallowing-whole. I imagine swallowing something as large as an adult human would leave it somewhat torpid and sluggish of movement, so it would probably want to drag such prey to a place of safety before eating them.
