“Search the Cellar” may sound like one of the most straightforward quests inBaldur’s Gate 3, but it isn’t. This cellar appears to be very plain, and it would be easy for players to think they need to wait for something exciting to happen first. But that’s not the case.
This cellar is like a very small dungeon, complete with puzzles, traps, riddles, and one ofBaldur’s Gate 3’s most intriguing treasures, the Necromancy of Thay. Unless you know exactly what to do, it’s easy to get stuck and give up. Between the lore and the value of the goods, however, it’s best to try and figure out this quest.

Thankfully, the fight is not too tough. In looting these caskets, players will find aScroll of Summon Quasit. Don’t save it as the Quasit has nothing interesting to say outside this area. Use it and gain some lore knowledge about the area.
