I have updated the rules file for my endgame variant for the Sands of Al-Kalim. When using this variant a player draws one card from a new epic challenge deck once they have acquired their 4th legendary item. The first hero to complete their epic challenge is the winner. The cards have been tweaked to make them a little easier and to add some fluff text to better tie them into the story. The updated card file can be found at
