Chasms

Chasms are large trenches in the ground that appear commonly in Corrupted ares. The depth of chasms seems to vary greatly; they can be very shallow and only drop down 100 ft. or so, or they can be very deep. Chasms commonly have Demon Altars and Shadow Orbs at the bottom which are only found in such chasms, often accompanied by chests and pools of water.
