@zkat You want to scare me, show me a Chute Crab, or more precisely a Scratched Vent. Run into one of those in a tight space, with an inadequate character setup, and you're doomed.
@zkat Ah, yeah, the Chrome Pyramid can be fairly effective in persuading you to flee the area in a rush. (I'd still rather bump into one of those than a Scratched Vent.)
