It is a DoS game, except with DND leveling, stats, and combat mechanics. Many of the stuff I find weird or backwards always traces back to DND rules. The 5e? rule book gets mentioned a lot. I don’t play DND and knew nothing about it before BG3. Learning the new level-ups, stats, calculations, and mechanics in BG3 is learning DND. There are a small amount of Sorcery point spells in DoS, but most of the spells in BG3 are Sorcery points. The normal spells that don’t cost sorcery points are called cantrips, and there are very few of them. I wish all the spell casters in BG3 were warlocks, as they play the closest to DoS spell caster classes, but only get 2-3 spell slots per battle. That’s 2-3 spells they can cast per short rest. It wouldn’t be so bad if everything refreshed on a short rest. And warlocks cast spells at their max level too, so you don’t have to be forced to cast level 1 spells at endgame like the other spell casters. Also, warlocks are pigeonholed into using 1 normal spell (cantrip) all the time, eldrich blast. At least it’s powerful and fun to spam.
There are also a bunch of ritual spells, which are not labeled when looking at the level up screen. They don’t cost spell points outside of combat. Talking to animals spell is one, which is nice for roleplaying/talking outside of combat (and I highly recommend talking to all the animals).
Conentration spells are also a mence, because you can only have 1 active per character. Summon a cloud? Need concentration for that. Summon a fire or rock wall? Concentration. Cast a buff on allies? Concentration to maintain it. Use them, but they limit the interactions a lot.
Talking about interactions, there are far fewer elemental ground effects and interactions. Some are in the game, but you have to take like 2 turns to do damage because most surface effect spells don’t do damage. Explosive barrels are still fun.
That being said, the new common actions (jump, dash, push, dip, etc.) are a great addition to the game.
I recommend the game still, because it’s mainly DoS with DnD combat. The story is better, and like the witcher, has a lot of heart and soul poured into the stories (and lots of sex and nudity, which can be disabled in options).
Also avoid fextralife wiki. Use the bg3.wiki as that’s going to be maintained better. (I’m not going to be talking about the drama with fextra here).
One last thing. The game is easier than DoS, and gets easier as you progress. I hope there will be a harder mode coming.
