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.
The defensive third of Force. Frost Guard raises physical resistance, Snow Shield pays part of the damage you take out of MP instead of HP, and the walls and novas freeze what walks into them.
Cold, Fire and Lightning are one mastery, not three. Taking Force gives you all of them and nothing stops you raising all three, so this is not a choice against the other two. Cold's imbue is the weakest of them for damage and the one people carry anyway, because it freezes what it hits.

8 lines · 40 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.
