Larian Studios Forums Baldur's Gate III Baldur's Gate III - Build Discussion Multiclassing -> what class to pick first?

Just found in a tutorial video , that you can even get important proficiencies also later on, for example through subclass war cleric, which means, you don't need to go for cleric 1st level to get your armour proficiency. So this all is starting to look quite complex without a proper summary. unfortunately.
