If you have the gold you can practice it for lvl 2 skill and use the seal for the 4 th slot . <| sep |> Here we go again with people thinking Mace Windu was winning against Palpatine . Palpatine had his light saber at Mace Windu ' s chest for about 5 seconds and could ' ve killed him . But for Palpatine to get Anakin to fully turn he needed anakin to kill Windu . So this , as with everything was a fight fully orchestrated by Palpatine and he was in full control the entire fight . This comes up a lot and there is evidence for both sides . However , especially in the current canon , we do not know which side is correct because it has not been explicitly stated . And I also don ' t believe that Stover ' s book is canon anymore .
