This is gonna be a lame normie question but I don't give a fuck, I don't play DnD ok.
Every build video I've seen always talks about "five three split barb wiz" and "eleven fucking fifty split whoremonger hentai master". Multiclassing? I'm about 40 hours in this game and I haven't seen anything pointing to multiclassing. Why should I do it and also how? The fuck? Levelling is mostly automatic, I just press the button and something awesome happens. How do I "split" my character?
Real AD&D doesn't have the same kind (and real D&D doesn't have any) of the "multi-classing" that exists in "D&D 3rd edition" onward, where a player-character, upon gaining a level, can instantly take a "level" in a different character class without any justification, allowing for ridiculously overpowered combinations. This is one of a dozen or so major exploits in Baldur's Gate 3, if you have a desperate urge to make the combat easier.
Yea, my first run is on Normal and I go through the game p. smoothly, without multiclassing or even respeccing (altho I will be respeccing Shadowheart today, who the fuck designed her attribute distribution? All she does in fights is cast Bless, miss a Guiding Bolt, then die. I might actually multiclass her, probably into a Pally so that she doesn't feel as useless).
Upon reaching 5th level, clerics gain access to 3rd level spells including spirit guardians, which creates an area-of-effect circle of damage around the cleric that lasts for a number of rounds (though requiring concentration). Even in Solasta, this spell was extremely powerful, and BG3 strengthened it by having damage applied at any time during the cleric's turn, so that the cleric can run around each round inflicting damage on as many enemies as possible; great against a large number of weaker enemies and useful in nearly every non-trivial fight. Granted, this still leaves 5th-level clerics underpowered relative to a fighter/paladin/barbarian/ranger/whatever who receives an extra attack each round, and also relative to a mage who can immediately cast
three fireballs haste in three non-trivial combats between long rests, thereby increasing the attacks per round of the fighter/paladin/barbarian/ranger/whatever to four accompanied by longer movement and an AC bonus.
