Larian Studios Forums Divinity - Original Sin Divinity - Original Sin - Enhanced Edition What do 2 levers in the cave at the beginning?

I have 2 questions, please answer who knows:

1) How many exactly ability points give for 1 talent point, in the Hall of darkness at the End of time?
The question arose because information found about it varies (could it be version dependent?), which is misleading.

2) In the cave at the beginning of the game there are 2 levers detectable through perception, both are in the same room, in opposite corners (see screenshots). When we passed through this cave, we did not touch them and at the same time passed through the cave normally. Later I came back, pulled them, there was some sound like something had opened somewhere, but what, where - I did not find.

The question is what exactly do these 2 levers do?

We play Divinity Original Sin Enhanced Edition v2.0.119.430

1. One.

2. They both open the Stone Gate to continue through the tutorial (there are also lockpicks there that can be used).

Thank you!
