Currently, mistlands is only dangerous for 3 reasons: Fall damage, knowledge about the enemies, and the gjall surprising you at times early on. Every single enemy is pretty easily evadable when you know what you do. Soldier cant fly and has a weak spot, seeker only flies if you are a certain distance away, so you are only at danger if you panic and run away from it. Ticks is all about aoe-ing them to death, and gjall is all about using the mountains and terrain to not get hit ... or just pop a fire resist mead.
First time entering mistlands I was scared to death, while now its actually higher chance of me dying in the plains to lo stamina rather than mistlands to surprises.
