Runepowder is not to be trifled with, as one Baldur's Gate 3 player (and their entire party) found out the hard way just how destructive a single barrel can be. The Underdark in Baldur's Gate 3 is one of the most memorable locations in the game, with plenty of good loot to be found in its depths. While the majority of the main plot in the Underdark concerns rescuing a True Soul, the path to get there can be accomplished in a plethora of ways. Arguably, the most straightforward option is dealing with Philomeen.
