I'm a fresh level 10 making my way through the Immaculates initiation trials… I found four pressure plates around the room and assume I need to place something special on them to unlock the blue forcefield before the rot kills me? Standing on them doesn't appear to work… I'm sort of stuck and any hints would be helpful guys.

In the meantime I did manage to bring down the bubble around the white witches house so I'll have a gander in there for now.

thanks disi,
I figured it was something simple... perhaps I was too tired to see it last night. ;-}
