Whoa i jumped into
"Scourge of the Depths Frox" big creepy monster
That thing may be stronger than Ganon so i ran away,but you what i can't find in those caves,a single shrine :^(
That one is pretty easy tbh. That thing... dislikes smoke. You need a few hammer-type weapons for it's actual weak points but that's it; and since it drops a pretty important item you'll need a lot of, I go and kill it every blood moon.
That being said, by Hylia, do I suck at combat in this game. I don't think I managed to beat more than one Lynel in BotW, if at all, and this game looks like it'll be the same. Hinox are easy as long as you can put yourself in a place where they can't reach you - top of a tree, cliff, hill, whatever is there works - then it's just Recall fiesta. Talus I can deal with, with enough hammers to break. Battle Talus I haven't tried. But Lynels? Gleeoks? No way I'll ever be able to win in a fair fight.
My only chance is to make some good contraption that kills them without (much of) my input, but that still a long way off; best thing I've done so far, with what was given to me (mountains south-est of duelling peaks, near a Black Hinox) was a little autonomous drone with a small tracked chassis, a targetting thingie and two beam emitters (there was also a canon available but I felt the extra energy drain wasn't worth it). I carried it for a while, slaughtering enemy camps, until I came upon a shrine, where I had to abandon it.
(since I have autohand and put it in my favourites I could build a new one whenever anyway, although the cost in zonaite is still pretty stiff for me atm)
