first this is a bug, but for me it is cool. it true form is a double sided spear.
I managed to get the full length of spear of leonidas even the ares madness ability is not activated. it doesnt have the glowing effect and work like regular spear and replace the weapon i use.
i hope ubi release this weapon with its own unique legendary affix.
Well, the curious thing is that the Spear of Leonidas in it not broken form exists and is in the files game.
But it seems to never had been implanted in-game. What a pity...
It would be cool to have it, just for the style or for doing cool photo. (It could have been a reward for finishing to reforge the broken spear at the forge)
