Coming from Divinity 2 to this is such a jaring, awful experience so far. For one thing, I find it laughable that the first combat you experience against the intellect devourers after you land is so insanely hard, I mean I had 3 straight critical misses and they crit me, the variance that the D20 system causes is simply absurd, and unfortunately unlike a real game of D&D there is no DM there to fudge the rolls in order to make the story work from a narrative basis, its completely RNG. I know some people might view this as whining but the reality is if you go into a combat, or perhaps even against a Boss, and you have literally no chance because of chaining critical misses then it takes all of the tension out of the game, it just becomes a slot machine to see if you were able to dodge the cursed run, regardless of how many attempts you make.
I am going into the third attempt against these devourers and I can tell that eventually the RNG will swing my way and it will work out, but it doesn't change that this system is nothing but a liability to the game and DOS2 proved that you don't need it. Just my 2 cents so far.
You can just bypass them by jumping up the cliff face on the right side or sneaking over across the right ship infrastructure and then go grab Gale, Lae'zel and Astarion and THEN fight them.
Or you can lower the difficulty setting until you are at a level that works for you and you have a better grasp of mechanics. The game definitely has a learning curve.
Without knowing what class/race I have no idea what your ideal strategy is.
