  // ATK per second, T2 ×scale_delta_to_one. PRTS 技能3 备注: "生命恢复的提供方式为基于铃兰的攻击力增加目标的“生命回复速度”
  // 属性，不受治疗加成和禁疗影响" and "技能开启第一秒内提供生命回复为0，生命回复速度数额每秒刷新一次" — an hpRegen buff (no heal:
  // 无法被友方治疗 / 禁疗 units get it too), set at each full second of the skill on the allies then in range, none in the
  // first second, removed when the skill ends. T1 技力光环·辅助: Supporters +0.4 SP/s (highest wins).
  // T2 画地为牢: sluggish enemies in range also take +20 % damage for the same time. Module (elite): +0.2 SP/s with an
  // enemy in range.
