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.
Harp
Support, and full intelligence: the dances and chords that lift a party, the ones that take the other party apart, and the MP a European party runs on.
Europeans have a potion delay, so you cannot simply drink your way through a fight, and that is why a party needs a Bard and a Cleric rather than merely liking them. Bard and Cleric is a build in its own right: fast, very hard to kill, and welcome everywhere.
Bard Mastery
10 lines · 56 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.
