Baldur’s Gate 3 Underdark holds surprising treasures beyond imagination. In addition to deadly foes like the Spectator, this underground area is home to abundant rare loot, a brand new fungal species, and this secretive place known as the Arcane Tower. Near the Selûnite Outpost, this Frankenstein-like lab demands players to conquer Arcane Turrets, fix mechanical elevators, and stay vigilant across its 4 floors to unveil its secrets.

The BG3 Arcane Turrets are tough cookies, shrugging off elements and physical attacks. Their laser beams pierce through any defense with a broad reach. Instead of a head-on clash, how about disarming these formidable foes?
