Guild Wars 2

I was watching the twitch stream from last week and had a question as to what happens when you use the eraser tool on a decoration?

The idea of creating a guild hall jumping puzzle intrigues me, but I’m a bit concerned that every time I erase one or more decorations I need to buy more of them or do the erased decorations go back into your inventory to be reused?

oops nvm I just didn’t watch the stream far enough
