The new area "rotten wasteland" has a mechanic that can make some player get stuck on floor for some seconds (there is an animation on character feet when it start and when it ends). Also, after you get rooted you got some seconds of "immunity" to get rooted again. This is the right moment if you want pass monsters to the ek. Watch out about get rooted near to the ek since some monster there give chain damage. People tell to each other they got rooted cause sometimes knight can lack of heal or another player could need help cause can't move.
