When I think of powerful monsters in Dungeons and Dragons, wights are definitely not what I think of. So why are they so dangerous here? They should not be more powerful than vampires and mind flayers.
And what exactly is the idea behind them stealing your buffs? Not really what I picture when I think of wights. But then again, wights aren’t supposed to be that dangerous. A level ten party should not have any problem killing a wight.
