Larian Studios Forums Divinity 2 - Ego Draconis (English) Help/Tips/Tricks Sound puzzle in Maxos maze?

Did a search, but couldn't find anything related to this.

There are four flagstones as far as I know that'll make different kinds of "click" sounds when stepped on, two on each location marked on the map below ("spoilered" to prevent messing up the board):


Anyone found a solution to this, if it even *is* a puzzle? Something to do with the locked, unpickable chest in the same area perhaps?

Hmm... I don't have the game installed anymore so I can't check.
Anyway, if you manage to discover the purpose of these things and (which is unlikely) open that chest - tell us :P

Will do. Wanted to get on with the story though; I'll experiment some more on next play through -unless someone chimes in with the, I'm sure, "obvious" solution first
