Ok here are my thoughts 80 hours in. I wanted a jolly cooperation souls game. This is a jolly cooperation souls game. And as a bonus, it's pretty damn hard. Solo isn't all that bad if you have lots of ER experience. The biggest hurdle will be Nightlords, but solo they have a tenth of the health compared to a 3 man team, so you end up chunking the fuck out of them. Plus you get a bunch of free revives. The current outstanding issues are that 80% of the relics are unusable due to the stats they give being completely pointless. Stuff like 15% throwing pot/knife dmg or 200hp if you have 3 flails in your inventory. The other big issue is matchmaking, if you go 5+ minutes without a matchup you're better off re-queueing because you're unlikely to ever get started. There's minor issues like target lock being shit, but that's the kind of stuff that will hopefully get fixed sooner than later.
Since I already talked about the classes, I'll cover the Nightlords
>doggy is the intro boss, super easy when he isn't split up, when he splits up just spam ults and chunk the fuck out of his HP, if you bring holy weapons it makes the split phase way easier
>big mouth fuckface sucks for melee when you're in a group, but solo he's super clean to fight; try to stay behind him, alternatively if you're a raider/guardian just stand in front and get eaten since your team can free you by hitting the head
>butterfree and metapod are annoying but the only real threats are that super charge shit he does, just split up when he goes apeshit and make sure to use fire dmg; if you're melee don't get so close that you can't see metapod's attack animations, he has a huge hitbox so don't be dumb
>jellyfish can go fuck itself, worst boss that FromSoft ever made all it fucking does is run away and spam sleep skills; in any case get some spammable aoe ahes of war to deal with the little pods he shoots out as killing those hurts him, you can also kill his fuckhuge egg bombs
>crazy goat is easiest if you do the mechanic, second hardest if you don't: you can easily break the sigils the first two times he does his meditation, and after that you can just alternate ults to stagger him out of it
>centaur is a joke if you bring lightning to stagger him out of his bullshit; when he charges around like a lunatic just spread out so only 1 person has to deal with the golden path
>dragon fucking blows, get fucked melee; nobody likes dragon fights in Elden Ring, and the tradition continues in Nightreign
>last boss seems like he'd be melee friendly, but nope he hops around so much it's almost impossible to get more than a hit in every 10 seconds; pretty sure a guardian with a lot of self heal and the dmg reflect relic could just block spam phase 2 to death
Some other tips for fighting Nightlords:
>prioritize weapons and spells that target the Nightlord's weakness, they make the fights far more manageable
>outside of that, debuffs, status effects, and %health damage is king; best spell being the humble Black Flame fireball
>if your char doesn't scale arcane and nobody else on your team is running bleed/poison/rot/frost, save your procs for phase 2; the amount of status application needed to do multiple applications on the same target scales really high, meaning there's a good chance you can go through phase 2 only seeing one of each proc if you already got two procs of each status in phase 1
>save ults to stagger the Nightlords out of dangerous abilities, unless you're a Recluse in which case use it for that sweet sweet opening burst damage
>buy starlight shards from merchants and feed them to your casters
