I was lvl 16 one of these things somehow came all the way down to hidden lake (my base) I was on single player so no one spawned it, it went after me. I killed the gosh be darned thing. It has 1000+ hp. Here's how: when killing them use spiked fences, Run behind the fences after making a small cage with a space behind to get out of. they will not run till they have -80 HP, then bows, spears, pikes, (I killed sarcos to get a pike) and crossbows works well, then finish it. It had no special loot. I was sad. Do this thing ^ if it worked!
