"Spike Wall" How to get behind them?

[Kirouna]

Hey Guys,
I've saw many Times, that there are some sort of "Spike Walls" in the Castle (Level 2) and there is a randome Item on a podest. So my problem is i can't get the Item cause the "Spike Wall" is closed all the way, there are some small gaps to shot through but not to walk through...

Do anyone know how u can get behind them to collect the Item?

The Dog pet can fetch the items for you. You can also use the Teleport Staff to get inside.
