I have... problems long resting as much as the game wants me to. Long rest classes give me stress. Also I don't really optimize builds much, but

• main character half elf fey warlock, pact of the chain
• wyll as pact of the blade
• laezel as 23 ac battlemaster sword and board. She's basically indestructible. Heavy armor master + adamantine armor means she can't be crit, and damage is reduced by 5.
• shadow heart as her default cleric, but honestly she's not pulling her weight a lot of the time. Spirit weapon is nice but misses a lot and has butt for movement speed. Spirit guardians is real nice, admittedly. Cleric cantrips kind of suck.

On the other hand, two warlocks with devil's sight and gith lady with an "immune to blind" ring is extremely effective. Shadow heart can chill out in the dark with spirit guardians, too.

Only in act 2 though we'll see how the rest of the game goes!
