// Player report D1 (community, after 0.1.0): "干员信仰搅拌机原版装备源石溶剂的装备带来的自动扣血会触发3技能的释放，这样配合
// 莫斯提马能自动叠层". Official (PRTS 卫戍协议：盟约 下半/PRTS盟约记录, 源石溶剂): the item's "每秒流失60点生命值" is corrected to
// "受到60真实伤害" (修正 原因 6, "并非流失"), 备注 "造成无来源真实持续环境伤害" — a damage instance, not a 生命流失 (PRTS
// 作战机制: a 流失 skips every damage event — 反伤, 受击回复 …). So the drain is a "受到伤害" for the 重装 技能策略 (PRTS
// 卫戍协议/帮助 "受到伤害时释放技能"), and 信仰搅拌机 S3's counter (PRTS 备注 "反击受到任何伤害后均可触发，无需目标，视为普通
// 攻击") fires on every drain tick, spending a bullet even with no enemy in range — next to 莫斯提马 (特质 "自身周围4格的干员
// 每消耗6发弹药，使已激活的【拉特兰】层数+1/+2") that is 拉特兰 layers with no enemy involved.
// The same `periodic_damage` template drives 狂暴宿主组长 (PRTS "自身每秒受到500无来源真实伤害"), and 孽罪奇美拉's pollution aura
// on operators is "受到…真实持续伤害" (PRTS) — both damage too. Operator 生命流失 (华法琳, 史尔特尔, 号角 …) stays a 流失.
