I am calm, trained to work different problems, have a proper lights, no silting.. but I don't have a cave certificate. We don't have any caves there. I have been in the flooded fortress few times, which is pretty big but not deep.

If you have something not difficult.. I am not crazy, so if it's above my level I understand that I still need to grow.
