Hello Everyone,
I just did this camp for my rogue (why I'm doing the side quests for the 1.0 epic, idk, but once you get one sword you might as well keep going, right?). I did see a polar cub on Martar's spawn cycle, and I do think (but am not 100% sure) that "a large wooly spider" is unique to Karg's cycle. I do not recommend doing this camp without a tracker. You can kill random spawns in the area between Megan's tower and the ice giant fort (at the split in the river and north of it), but it will be easier to do this (which is the same as Scuba prescribes): Kill a bunch of mobs in that area until you get a polar bear, polar bear cub, a large wooly spider, or either ice goblin whelp (without the an) or an ice goblin scout. Once you get one of those mobs, wait about 20 seconds, as Scuba's post prescribes, so you don't get confused after you kill one of those mobs on what is respawning. The respawn time is around 8 seconds give or take. I left my tracker's filter on normal because that seems to order them by spawn time. My tracker's skill was 200.
I hated doing this camp lol, but it is intriguing the way it is done, and that kept me coming back. I had to spawn Karg 4 times before he dropped the gigantic Zweihander, so it was about 2-3 days of about 6 hours a day. But, it could always be sooner. Again, I don't recommend doing this camp without a tracker; I tried for the first day, and I actually did get him to spawn, but once I got the tracker, the spawn rate went up. Good luck and good hunting.
