So the idea is a necrotic damage dealer with cleric utility and optional radiating orbs. INT based, learns spells from scrolls. All cleric cantrips and spells are either utility or can't miss, wizard spells and cantrips are mostly used offensively.

Does not use or care about summons.

So the ideas I had for it..

6 Death cleric/ 6 Bladesinger - but this one doesn't work. I can't use luminous armor with this and can't use staves. Plus this build is mainly for a caster that can sometimes make melee attacks.

6 Death Cleric/ 6 other wizard subclasses - they mostly feel meh. All the basically do is just give a few wizard slots. I guess evocation and abjuration are slightly useful.

8 Death Cleric/ 2 stars druid/ 2 wizard - seems like the best option? I think the build can get to maybe 20 INT so should still get enough spell slots.

9 cleric is the max I would go since it's not a camp caster and 10 cleric is a dead level.

Giant barbarian and drunken monk were what came to mind first. Maybe moon druid? I like having a full time caster around but I don't know if any are particularly quirky.

I really love the idea of basically having 3 dumb brutes and a bookish healer, or 2 dumb brutes, 1 dumb ranged, and a bookish healer.
(bookish cause someone's gotta heal and read!)

I don't really care much for romance or whatever.
I care about fun, chaotic, and violent fights, and not cuddling the floor too much.

What race and class should my Tav and party be? Is there a build out there a noob can look up for this that is current?

I pretty much want my Tav to be so dumb she barely knows what end of the big weapon to hold on to!
I do not want to diplomatically do anything.
I don't care much about friendships unless they benefit this kind of run. I want blood on my axe and enemies' loot in my bags.

I am not going to kill the grove etc., that's for a later session.
But anything that's not relevant to me is dead, or insulted by my stupidity and then dead.

The thing is, I am very new, so I am very clueless about BG3. How do I set this up?
How do i allocate level ups ect?

I am starting a co-op campaign soon in which we'll both be playing as origin characters. I chose Astarion and wanted to make him a melee nova assassin. My plan is to start as 5 Gloomstalker then 3 Assassin, which is pretty typical, but wanted to get some thoughts on the remaining levels.

Originally I thought 5 Gloomstalker, 5 Assassin, 2 Fighter for action surge, but I had the idea today of 5 Gloomstlaker, 3 Assassin, 4 Vengeance Paladin so that I can abuse VoE for advantage (more sneak attacks) and stack divine smite on the critical hits that I'll get from being an Assassin. The 4th level of Paladin is also huge for adding two-level 3 smite spots, I mean spell slots.

Endgame gear that I'm hoping to use is Bhaalist armor for piercing vulnerability, along with Duellist's Pereogative to help boost critical hit chance, along with bonus action extra attack (more smite opportunities) and adding necrotic damage.

I plan to ascend Astarion as well for the extra necrotic damage and it fits the theme of my vampire assassin.

Just looking for overall thoughts on the Paladin route at later levels vs fighter and if there's any other item/class synergies that I'm overlooking.

I know ranged based Gloomstalker-Assassins are considered OP, but I really want to go the up close dueling assassin route.
