Ooooh sounds awesome! Are the mods that already exist good so far? =)
It's hit and miss. You have to be careful though. I would recommend not using any mods, that change the game files. I only use mods, that go into the Mod folder. After patch 4 for 2 weeks I couldn't use any mods. Then I found a new Mod Manager that worked. https: //github.com/LaughingLeader/BG3ModManager. Here's the list of Nexus mods that I use:
5e Spells, 5e Cantrips, Feats Extra, More Feats, Expanded Backgrounds, Dodge Action, Powerful Characters (I use the Legendary version), Level Up, Patch 3 Mod Fixer, Playable Paladin, Sorcerer, Expanded Cleric Domains, and the Bladesinger Subclass.
There is a conflict with the Level Up and 5e Spells mods, that takes away the Flaming Sphere spell. The 5e Spells mod turns it into a mini Fireball, that sets the ground on fire. The Level Up mod eliminates it from the spell list. So be warned. It's not a permanent change, remove the mod, it works as normal.
Cool! And those mods are good? I mean, does it work well within the game?
