Plains of Havoc Giant Spider Hole

The Plains of Havoc Giant Spider Hole is, as the name suggests, a hole on the Plains of Havoc, which is home to a single Giant Spider. It is situated a bit south of the Plains of Havoc Temple, to be exact. One of the last Nightmare Knights, Camdrek, fell down this hole on his way to Knightwatch Tower and was killed by the Giant Spider. Nowadays, you need a Shovel to open the hole. But before Update 8.2, this hole was a Pitfall and creatures could be lured into it. This happened often, and upon falling (or being pushed) into the hole, low-level players would usually die instantly and with 5 or more Giant Spiders around it was not uncommon to see players of level 100 or above die as well.
