I love the challenge. Haven't had any reloads due to deaths yet, but there was one fight where it came close until I figured out a better strategy.
I really hope that whatever this difficulty level is remains the standard difficulty and other options are implemented around it.
I've been very vocal in this thread but I did really start with asking how people are getting through the fights. I'd love to know what you did for the goblin gate fight, if you found that challenging? Also how did you find the Gnoll camp or the true soul goblins.
I do really think I'm missing something here.
I've been employing the same handful of tactics for a little while now. I'm a Warlock, and I've got Wyll, Gale, and Astarion with me, so we're 3 casters (but kinda 4 since Astarion is Arcane Trickster.)
Because we're all extremely squishy, I play keep-away. I usually use my hardest hitting spells on what I perceive to be the most dangerous target to take it out of the fight immediately, and then it's a game of cat and mouse as I run away as far as I can, jump up to ledges, whatever I can do to create space. If something gets close, it either gets a push or a thunderwave. I also make a point to move into a ledge that I've jumped up on just a bit in the event that an enemy clambers up there with me. That way, I can give them a shove off the ledge, cause more damage by simply being defensive, and take them out of the fight for a second by knocking them prone. You can also abuse line-of-sight and move around small corners or adjacent rooms and force targets to funnel in toward you. Melee typically heads right for you, and ranged tend to expose themselves to get into position to hurt you.
I don't know if it's supposed to be easier or harder with 3 dedicated spellcasters, but I've been having a good time in every fight looking around the environment for high ground, planning retreat paths, and giving myself as much advantage as possible.
My biggest challenge thus far has been the harpies because they're also ranged, and dive into battle for attacks and retreat with huge movement advantages. And the area is
painfully wide open. Almost lost that fight until I switched up my strategy.
