how to get into the arcane tower bg3

Quick Scoop

To get into the Arcane Tower in BG3 , head to the tower in the southwest Underdark, then use the mushroom route along the outside instead of trying to brute-force the front door under turret fire. Once inside, grab a Sussur Bloom , bring it to the power generator, and combine it to restore power and activate the elevator.

Fast route

1. Reach the Arcane Tower in the southwest Underdark.

2. Avoid or disable the Arcane Turrets; they guard the entrance and can be handled with Sussur Blooms.

3. Go out the southern balcony and jump across the mushrooms/climbable flora to reach the lower exterior path.

4. Pick up a Sussur Bloom from the glowing tree area outside the tower.

5. Open the locked door or force it, then use the bloom on the generator and combine it.

6. Take the powered elevator to move between floors.

Useful tips

• Arcane Sentries are notably vulnerable to Lightning damage.

• Be careful near explosive mushrooms on the approach.

• If you just want the shortest answer: go around the outside, get a Sussur Bloom, power the generator, then use the elevator.

Why it feels tricky

The tower is designed to look sealed off from the front, but the real solution is traversal plus the Sussur Bloom mechanic. That’s why many guides focus on the outer mushroom path and generator rather than the main door alone.

TL;DR

Reach the tower from the Underdark, use the outside mushroom path to get in, grab a Sussur Bloom, power the generator, and activate the elevator.
