The way to activate the rising button of the arcane tower in Baldur's Gate 3 is very simple. It mainly uses flowers and machines from the underdark to synthesize them and then activate the button. There is nothing in this tower that requires the player to be in the tower. Search on the first floor.
Answer: The button can be activated by combining flowers and machines from the Underdark.
Players can first see mushrooms outside the tower, and jump over them to reach the first floor of the tower.
On the first floor, you can see flowers from the Underdark, which can then be synthesized with machines.
After the synthesis is completed, you can turn on the switch button and directly select the elevator to rise.
