Larian Studios Forums Baldur's Gate III Baldur's Gate III - General Multiclassing spells

I create 5th level multiclass character with Charisma 18:
Bard 2 level, Paladin 1, Sorcerer 1, Warlock 1

Does this mean that my character will have :
4 spell slots level 1, 3 spell slots level 2, 2 spell slots level 3 for bard
4 spell slots level 1, 2 spell slots level 2 for paladin
4 spell slots level 1, 3 spell slots level 2, 2 spell slots level 3 for sorcerer
2 spell slots level 3 for warlock ?

Will this lead to a strong imbalance in the game?

Does the Larian studio plan to release a manual to multiclassing before release of the game?
