The player can't, at this time, dig a cave. One may dig a trench and cover it with structures but that is a lot of work. Haven't tried a Burial Chamber or a Troll Cave. The Chamber seems awfully cramped for a portal. A cleared out Troll Cave wold have to be close to the shore to be worthwhile.

Thanks, Yes I've dug out under a copper deposit . Worked fairly well to keep a troll from squashing me. I have yet to find a troll cave, but since a troll lived there, they could enter to kill me I think.
