Upon reaching level 50 with a character, one unlocks their mastery skills.
Each character has three mastery skills, but only one may be chosen, and it cannot be changed.
Mastery skills come in the form of very powerful passive abilities, and on occasion an incredibly useful spell or attack. Most are designed to be used with specific skill trees, while others offer universal benefits.
Upon reaching level 60 with a character, (leveling beyond 50 can only be done once the player has at least 4 level 50 characters), they are then free to change mastery skills from one to another as they see fit.
