has_mastery 常用于设计国家专注树或决策的解锁条件，例如要求玩家在特定兵种方向积累足够经验后才能触发强化性奖励，从而鼓励玩家专注发展某一作战路线。在自定义战役 mod 中，也可用它来分阶段释放剧情事件，使叙事推进与军事成长挂钩。
# 当步兵精通达标时才允许触发某个决策
available = {
has_mastery = {
amount = 150
track = infantry
}
}
[has_completed_track](/wiki/trigger/has_completed_track)：常与 has_mastery 并列使用，前者检查某条路线是否已全部完成，后者检查累计精通量，两者共同构成"质量 + 数量"的双重门槛。[add_mastery](/wiki/effect/add_mastery)：作为奖励效果与该 trigger 配合——先用 has_mastery 判断精通值是否达到阶段目标，再用 add_mastery 叠加额外奖励，形成"检查 → 奖励"闭环。[add_mastery_bonus](/wiki/effect/add_mastery_bonus)：用于在精通量满足条件后进一步提升后续获取速率，与 has_mastery 配合实现滚雪球式成长设计。[has_completed_subdoctrine](/wiki/trigger/has_completed_subdoctrine)：精通值往往与子学说解锁挂钩，两者结合可精确限定"解锁了某子学说且精通量达标"的复合条件。track 字段值拼写错误：track 必须填写游戏内实际存在的精通轨道标识符（如 infantry、armor 等），若拼错或使用中文名，trigger 会静默失败（始终返回假），且不会给出报错提示，调试时极易忽视。Hands-on notes are AI-generated and checked against the vanilla command vocabulary — treat them as a starting point, not authoritative reference.

has_mastery is commonly used to design unlock conditions for national focus trees or decisions, for example requiring players to accumulate sufficient experience in a specific unit type before triggering enhancement rewards, thereby encouraging players to focus on developing a particular combat line. In custom campaign mods, it can also be used to release story events in stages, linking narrative progression to military development.
# Only allow a decision to trigger when infantry mastery reaches the threshold
available = {
has_mastery = {
amount = 150
track = infantry
}
}
[has_completed_track](/wiki/trigger/has_completed_track): Commonly used in conjunction with has_mastery, the former checks whether a track has been fully completed, the latter checks cumulative mastery amount, and together they form a dual threshold of "quality + quantity".[add_mastery](/wiki/effect/add_mastery): Functions as a reward effect paired with this trigger—first use has_mastery to check if mastery value reaches the phase goal, then use add_mastery to stack additional bonuses, forming a "check → reward" loop.[add_mastery_bonus](/wiki/effect/add_mastery_bonus): Used to further increase the acquisition rate thereafter once mastery amount meets the condition, working with has_mastery to implement snowball-style growth design.[has_completed_subdoctrine](/wiki/trigger/has_completed_subdoctrine): Mastery values are often tied to subdoctrine unlocks; combining the two allows precise specification of the composite condition "unlocked a certain subdoctrine and mastery amount is reached".track field value: The track field must contain the actual mastery track identifier that exists in the game (such as infantry, armor, etc.). If misspelled or if a Chinese name is used, the trigger will silently fail (always return false) without an error message, making it easy to overlook during debugging.
