Inca, just to let you know where I'm at mentally in this scenario, Storm is going to wait until Zach is in position and can hopefully give a scouting report as to what's inside the 5th floor. Once we know what we're up against, Storm's going to have her spirit knock a hole in the wall big enough that she and Stake can get through. Hopefully the Silence spell keeps the noise down enough that they can keep some element of surprise.
