Okay so,, I just downed one. I thought I was on a high enough ledge so that it couldn't reach me. Surprise! She disappears for a moment and then pops up in my face, talk about jumpscare of a lifetime. She knocked me off into a hole and I shot tranqs into her face until she almost had me dead but she ran off and passed out on a very hard to access part of a cliffside. I've gotten stuck there twice. My advice: find a hole you can get in and out of easily. Shoot tranqs into their eyes until they run off. Suckers are fast, so you're going to have to pursue them.
