From what I understand Combat Minion seems to be a GM tool for managing combat. XP Tracker is a player’s tool to manage progression through the game as well as combat. It was designed to speed up game play by handling everything from die rolls, adding all bonuses together, managing skills and items and more. Basically the scratch paper you have in front of you to add up all your attacks, take notes is replaced by XP Tracker. I can safely say it saves trees
Best of all, when the game is over you don’t need to sit around figuring out all your earned XP to see if you level up, it’s all done during the use of XP Tracker. But XP Tracker can be used in conjunction with Combat Minion. Watching their video there is a manual input for player rolls that they would add in manually.
Here is a video I put together to show you the set up and use of XP Tracker.
