It's not melee because I went with my team after that clip and asked the knight what kind of damage was he taking, he told me mostly fire, the thing is that our knight is 900, average level of our team is 700+ so the damage taken is not form the mechanic since none of us ever get close to the knight, he tanks all the reapers and we kill the boss with fire balls (single target fire rune) so that way we don't have to kill the reapers and they stop spawning after 6, but I starting to play on new servers so i want to figure at which level a knight can tank this boss but for that I need to know what ability set the boss has to use the best protection
