  // cast hit nothing for 26 s); enemies in range take +10/11 % of his ATK true damage from every Kazimierz attack. Per
  // PRTS 备注 the trait bonus drops by 10 % (per_kill_reduce, absolute: +400 % → +390 %) for each enemy knocked out by
  // his own attack (or the damage it carries — not 无动于衷's reflection, not a mark another operator's attack set off),
  // settled after that attack, never below +0 %. T1 游侠: ×1.1 ATK on attacks (×1.15 and −15 % damage taken with ≥3
  // enemies around). T2 无动于衷: taunt +1, Kazimierz ops reflect 15 % of his ATK as true damage when attacked.
  // S1 未声张的怒火 (duration, SEARCH): attacks attack@atk_scale × ATK, DEF +. S2 未宽解的悲哀 (duration): skill range,
  // BAT +0.3 s, attacks attack@atk_scale × ATK twice; a kill of his own attacks during the skill keeps the trait ramp
  // when it ends. S1 / S2 have no 对空 note: ground only, like his trait.
