Slate Butterfly Jacket

The Slate Butterfly Jacket first appears in Book 5 as a deceptively soft, fur-lined garment that conceals a swarm of slate butterflies—each equipped with pull-tags that, when released, seek out and swarm light sources. Its utility lies in its ability to disrupt enemy vision and create tactical diversions during the chaotic Butcher’s Masquerade, marking it as a stealth-and-support tool rather than a traditional piece of armor. Across the series, the jacket evolves from a one-off loot drop into a recurring symbol of Carl’s growing preference for clever, non-lethal crowd control, its butterflies later referenced in subsequent crawls as an early example of his penchant for turning seemingly innocuous items into battlefield game-changers.
