  // ===== 缄默德克萨斯 (executor) S3 剑雨滂沱 (passive) — deploy burst 2×115 % + 1.5 s stun, sword rain 1/s; talents
  //       S1 细雨无声 (passive, for the skill duration: ATK up; hits silence the target 5 s/8 s — 失去特殊能力 — with
  //       260/320 arts per s meanwhile); S2 阵雨连绵 (passive: deploy burst 150 %/180 % arts + RES −15 %/−20 % around her;
  //       for the skill duration ATK up and attacks become arts double hits). Talent 德克萨斯传统 applies to every passive.
  //       The S3 rain hits air units (PRTS 备注 "效果可对空"); so does the S2 deploy burst [ASSUMED: no note].
