He could have backstabbed him literally, but its the wound (i.e. bloodloss) that killed him in the end Um, if you're referring to The Old Republic - it isn't.
which one? there's like three types of Maul in tcw - one with spider legs and bandages, one with fancy biped cybernetics and horns, and one looking 'civilized'
Speaking of which, could you also add this head to the standard K2 jedi robe? It's from a mod, the Exile's canon appearance (basically a retexture of one of the vanilla heads)
There is an old jedi_hm expansion pack that add a number of outfits, including K1 robes, though those are just retextures, and are of pretty low quality. Sadly, that's all I know.
