Any tips? Having a hell of a time dealing with one spawning at the bottom of the river near Echo. It's pretty much stuck in the river and I'm about to get the damned deadly wisps coming along. Thankfully my gamestate is such that I can sell a bunch of MREs to cure radiation and stock up a bit on heals, but fighting one of these underwater while wearing a hazmat suit just sucks..

Edit: Took numerous tries, but finally did it. Best to take small breaks between phases and refocus, immediately leaving the river and healing if you take two bad hits. Best also to remember to use shift and stay in its face as best you can as you circlestrafe, Have to be right on it and try to remain on the riverbed while also not running out of air.
