Master's Datacron allows you to instantly level up to 70 of any character below the maximum level. The peculiarity of this item is that it does not affect the story of the character. Right - click on the datacron in your inventory (make sure it's used by the character you want to upgrade)! An 8-second activation bar will appear, indicating "level 70 Upgrade". When the bar fills up, you'll see two pop-up messages asking for confirmation that you really want to boost the character. Note: this decision is final and irreversible. Now you should look in the discipline selection window (default is K button) to select a discipline for your class if you haven't done so before. After selecting a discipline, right-click on the box with equipment in the inventory and you will receive a full set of equipment with characteristics depending on the selected discipline.
