They go after unconscious people wayyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyy too hard. If I did that as a DM my players would burn me at the stake.
Seconded. Watching every goblin archer in the camp try to shoot my dropped wizard with disadvantage and missing shot after shot while my two fighters drop their friends like flies is... weird.
The way I got through the goblin camp was to use his brain slug ability to reflect projectiles - arrows, bottles...reflects them all. Its a nod to the fact they know it happens but it puts an uncomfortable onus on the illithid powers when you might not want to, but man that is SO HARD without it.
First of all, I don't see the death problem to be that big of a deal considering how easy BG3 makes it to resurrect folks. 200g is super easy to come by.
The second issue is that perhaps attacking the goblin camp head on isn't really the smartest decision and you are being punished for that. There are numerous paths you can take to assault the goblins from high ground that would be far, far safer. The goblin camp is a classic action economy disadvantage. You need to make use of other advantages (like terrain) to win. Your character is a wizard. They presumably have a 16+ INT, they should be smart enough (from an RP perspective) to not assault a full camp of Goblins on even terms. Also you could alternatively go for the stealth approach that is recommended by like 3 different NPCs (e.g., come in over the back side, assassinate the passed out drunks, and go in through the roof, sneak in and attack from the rafters). Or you can run with a +5 in persuasion and get by that way. You don't have to use the power word authority at all.
