MasterSkillTree.txt

Per-master-level skill progression table. For each master skill, defines 20 values (level 1-20 progression), prerequisites, replacement chains, and per-class Rank gating.

File Location#

Data/Skill/MasterSkillTree.txt

Loaded once at GameServer startup. Changes require a restart.

Format#

Whitespace-delimited. One row per master skill. First comment line names the columns. Terminated by end. Numeric values in MainValue1-MainValue20 are parsed as floats; all other columns are integers.

Columns#

Column	Effect
`Index`	Skill index from Skill.txt
`Group`	Tree group. `1` = left, `2` = middle, `3` = right (three master trees per class)
`Rank`	Vertical tier within the tree (`1` = base row, `9` = top row). Higher ranks require lower-rank investment in the same group
`MinLevel`	Minimum master level for the first investable point in this skill. Typically `1`
`MaxLevel`	Maximum investable level for this skill. Fixed at `20` in S6.3; values above 20 are clamped
`MainValue1` ... `MainValue20`	Effect magnitude at invested level 1 through 20. Parsed as floating-point; per-level curve is pre-baked in the table, not interpolated by formula
`RelatedSkill`	Skill whose effect also benefits from this row's bonus (e.g. an "Improved" node boosting a base skill). `0` = none
`ReplaceSkill`	Skill index that gets replaced on the active bar when this node is learned. `0` = no replacement
`RequireSkill` (first)	Primary prerequisite. Must reference an `Index` in this file. `0` = no prerequisite. Both header labels in the shipped file are the string `RequireSkill`; this is the first of the two
`RequireSkill` (second)	Secondary prerequisite. `0` = not required. When both are non-zero both must be learned
`DW` / `DK` / `FE` / `MG` / `DL` / `SU` / `RF`	Per-class visibility and tree position. Non-zero = this class sees the node at that ordinal position in its tree; `0` = the class does not see this node

Tree Semantics#

Group - which of the three trees a skill belongs to (left/middle/right columns in the master UI)
Rank - vertical position in the tree. Higher Rank requires at least one investment at every lower Rank within the same Group before becoming learnable
MainValueN - effect magnitude at invested level N. The server looks up the value for the character's current invested level directly; it does not compute intermediate values between the 20 entries

Relationship to Common.dat#

Common.dat Master Skill Tree Settings controls global gates:

MasterSkillTree = 1 enables the tree
MasterSkillTreePoint = points per master level
MasterSkillTreeMaxLevel = master level cap

Common Issues#

Skill available too early - Rank too low for the intended progression; reorder within the Group
Per-class rank shows zero - the class column is 0; set to the non-zero position that class should see
MainValueN progression too flat - regenerate the curve; shipped values follow a tuned diminishing-returns shape
Prerequisite skill learned but dependent still locked - one of the two RequireSkill columns points to the wrong Index, or the required node has not reached at least level 1
Replace not applying - ReplaceSkill must match the exact Index of the skill being replaced in the active bar
File edit ignored - missing end terminator or a malformed MainValue token; parser drops the file on error
