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.
Spear · Glaive
Spear or glaive off the same tree, and both of them two-handed: the client says so in its own words, that the technique only focuses on offence and you cannot use a shield with it. The glaive is built full strength and the spear full intelligence.
Heuksal and Force. With no shield anywhere in the tree it buys its defence in other ways: Fanning Spear raises magical defence and magical block rate, the Cheolsam passive adds maximum HP outright, and Immortal Victor shares the damage out across the party. The offence is what it is known for, stuns out of Soul Departs Spear, knockback out of Ghost Spear, and chains that run to seven hits.
Heuksal Mastery
9 lines · 45 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.
