That was my first thought when somebody mentioned legendary actions that they are rarely a thing in mid level adventurers like ours in BG3 going to be.

But who knows anything can happen, Larian can add their own homebrew creatures.

On the other hand, we are fighting the little brain thingies at level one. I don't think we will have to wait until level 7 to see our first mindflayer either. This will probably be a deadly adventure with no hand-holding, so we may face some op enemies in full release.
