【已废弃】古老三叶结货币，曾用于在军械库调整勇气、优雅与灵性。Preludes 15 起已取消消耗品机制，美德比例现可在军械库免费调整，页面仅作版本与背景说明。
Removed in Preludes 15 (Gods & Ghosts): Virtue ratios are free per loadout in Arsenal — Virtue Lith no longer drops, crafts, or spends. Community catalogs list Virtue Lith without a Drop Sources table (checked 2026-07-23), so there is no verified farm loop to document. For current virtue math, open Arsenal → Virtues / Balance and read our virtues explained guide instead of hunting this currency. Legacy inventories may still show the icon, but new players should ignore acquisition guides that predate the removal.
