I did some more rots today. When you get shadow realm'd everyone on both sides goes in for the remainder of the kill. All of the brother's *SPECIAL* attacks do extra damage (double I think, but not sure). Bombs and spins appear to do normal damage. Basically, if you get a spear in you, you are going to die if you don't get it out in 5 seconds. Wall jumps do about 4k damage, and you take constant 500s when pounded in to the ground. At the start of the kill, there is one brother that says "You dare to disturb the shadow!" which will be seen in your chat box. This is the only brother that can shadow you, so you can choose to focus him in order prevent getting shadowed.
