Fly higher! Also the spawn info for them is in the Google doc linked in the description. If you want to disable them, you'll want to disable the boss version.

Its just insta-kill me and my max level PT. All my armor just breaks immediately. Something is out of whack for the fen and vapor golems. I've only run into those so far.

They're super aggressive to all fliers, so the best advice is to avoid them until you can kill them on the ground. Fen is easy, grab a lightning creature and go to town. :) The Google doc also lists out strengths and weaknesses of the elements. :)

Ok, I'll get good. Sounds like I have lots to learn. I didn't research the mod before I installed it. Nice work by the way. You've really added tons of variety and mechanics to something I've spent over a 1000 hours in. This new play through actually feels fresh.

Good luck and I hope you enjoy! :)
