For CC users with UO Assist, the "-where" command will give you your coordinates without using a compass.
There really aren't that many roads for Krampus to spawn along. There's 2 major N/S roads, and 2 minor ones. Each falls within a narrow range of Longitude. (Yew to Skara, Britain to Trinsic, are the majors. The minors are East Brit to Compassion crossroads, and Buc's Den teleporter to Minoc (and a third even smaller paralleling Vesper coast).)
There's one major E/W road - Yew to Vesper. It's got a larger range in Latitude, but still would be a recognizeable range. The minors are Minoc Mines/Vesper, and the Britain/Skara road.
Figure out the coordinate ranges of those, and you should be able to figure out an approximate location for most spawns, unless someone is going cross-country from Trinsic to Skara, or taking one of the north Brit mountain passes to Yew instead of the West pass.
