The Suggestion Box is an object found in Scarlet Briar's secret room within Twilight Arbor. It's only accessible by having a player follow Caithe in path 3 of Twilight Arbor (explorable) after the final boss has been defeated. Interacting with the box spawns a level 80 Veteran Twisted Nightmare that will award players the Broken Clockwork achievement when killed. If 5 players are in the room when the box is activated, a Champion Twisted Nightmare will spawn instead.
- This object was added to Twilight Arbor with the October 1st, 2013 update, as part of the Twilight Assault release.
- The Suggestion Box is identical in appearance to the Box o' Fun.
- Unlike other Twilight Arbor Aetherpath achievements, Broken Clockwork is only rewarded to players who participate in the objective directly; in this case, killing the Twisted Nightmare. The gate to Scarlet's secret room will also close shortly after Caithe enters, making it impossible for players to get the achievement if they weren't able to get there in time.
