If someone wants to test this with me I've been trying to see if turning in the skulls to the cauldron in the 2nd phase of the DK starting zone would do the same thing. It takes 20 crusader skulls and is repeatable.
This does work but I just need to find a way to make it time efficient. At the moment there are no mobs in the area that spawn quick enough to ever make this time efficient. Disregard.
