Diablo 4 isn’t known for its intense puzzles, but Vessel Of Hatred is shaking that up a bit with its series of event puzzle chests, of which the brazier puzzle is the third. Whether or not you decide to make a new character, you’ll run into these braziers eventually. This puzzle also appears as part of the main questline “All Good Things,” so you’ll need to know how to solve it to progress. The puzzle series version of this puzzle can show up in any standard cellar, making it tricky to track down. Once you find it, you’ll be faced with the even trickier challenge of actually solving it.
