Guild Wars 2

I got the hand upgrade. I’m trying to use it on this door but nothing is happening. Is there something else you have to do first? It looks like there’s something behind the door.

I expect you to run infantile mode.

You should’ve come from the floor into the room; so you’re seeing the backside of the destructible wall. Turn around and go the other way.

Concerning this door, I haven’t been able to figure this one out. Correcting the above post, this does not matter if you are on infantile mode, there just does not appear to be an obvious way through this barrier. The hand symbol is different with an arrow pointing down and the hand ability does not work. It seems to indicate there is a switch of some sort below but I haven’t been able to find anything that looks remotely suspicious (did find a dig site though).
Anyone been able to figure this one out yet?

(I have a hunch it’s something to do with the block puzzle below but it’s defeating my best efforts so far)
