Boss rush Skill tree

[Mex]

Just a single node from me which I think should be somewhere towards the end and I thought of a smoke bomb that you could throw at your feet and it would put people into the shadow step realm like assassin t class for x seconds so it would be somewhat of a flee / mobility mechanic to keep people alive. I don't know if people still bunch up in br but I know we did they back when it was first released. Obviously giving a cooldown to the user and if other people who have that skill go with the initial user they get half the cooldown time.
