Skills
Every skill a character can learn, laid out the way the game's own window lays them out: a race, a tab, a mastery, and the lines of skills within it.
Dark staff
Curses, bleeds and burns rather than one large hit, plus the debuffs that stop a target healing, moving or casting. Full intelligence, as the casters all are.
Rarely the mastery that kills, reliably the one that makes the kill possible. Warrior and Warlock is rated among the strongest PvP pairs in the game for exactly that reason.
Warlock Mastery
13 lines · 72 skills
Each row is a line of skills and the icons along it are its successive versions, which is how the game's own window draws them: the number on an icon is the skill's highest level, and pointing at one shows it at that level. The grid, the rows and their names are the client's own, and every number on it, mana, attack power, skill points, cast, cooldown and range, is read out of the game's files and fitted against its own tooltip. What a mastery is for, above, is the one thing here that is not: that is what the community says these trees are for, checked against the build guides rather than written from memory.
