Larian Studios Forums Baldur's Gate III Baldur's Gate III - Build Discussion Action or Attack progression by Class / sub-class

Hello,
Is there a way that wizard or cleric would have two actions in a turn ?
I understand that Fighter has extra attack. And that is an action.
Although , to me , an action is a broader term than an attack - which is more a specific action.

Thus everyone is adding Fighter as multiclass to have more attacks.
I see in game that enemy has more than two actions. And I can not keep up with them in number of attacks and damage output.
Besides most of my attacks are misses.
