Resonant boss kills are the express stops on the Manhattan map. They unlock the control resonant key(https://www.lootbar.com/game-k....ey/control-resonant- ) for new Manhattan zones and permanent ability upgrades. Repeatable minor encounters are scenic detours; they give no long-term progression value and should not consume a zero-spend player's early hours. Spend early Talent Points on Execution health recovery and the 8-second Dominance buff duration first.
