We need some guns and a witch.
We already have a scientist witch who makes the BEST explosions. We just have to meet up with her again. :P
I know; that's exactly the point.
Guns can be provided (Jessica and Chloe were stockpiling before this). As for the witch, well, you're going to have to go find Lyx again... ;)
I think I remember seeing some near the manor door entrance/exit xD
