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.
Light staff
Heals, cures, resurrection, armour and the party buffs. Only seven of its seventy skills do any damage at all.
The most common second mastery on the European side by a distance, taken beside Warrior, Wizard, Rogue and Bard alike, because the potion delay means a party has to bring its healing with it. The stat changes neither the healing nor the buffs, so either one works: strength buys survivability, intelligence buys damage on the seven skills that have any, and nobody brings a Cleric to a party for those.
Cleric Mastery
14 lines · 70 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.
