How the hell would Malak defeat Krayt? Lol.
Malgus has proven that he can defeat Satele, and even Ant admitted that Malgus is a challenge for Revan. Kun is an equal duelist in terms of feats and capabilities to Malgus, he can likely press and eventually defeat Satele after an exchange. Malak isn't lasting long against Krayt, and Revan can at best stalemate Malgus until Krayt or Kun come to aid him in finishing him off
Team 2 should take this with mid difficulty.
