Mangy Wig

The Mangy Wig is an uncommon head armor in the Used set that spawns one Spiderling familiar at the start of each battle for every 4 points of Luck the wearer has. With 8 Luck you start with 2 Spiderlings; 12 Luck gives you 3 — and so on. The scaling makes it increasingly powerful as Luck accumulates across a run. It references Mom's Wig from The Binding of Isaac, which works on the same principle.

Luck-stacking items like the Cat Paw (+2 Luck) and Lucky Hat (+1 Luck) directly feed the Mangy Wig's output. In a run where multiple pieces grant Luck, the Wig can field a meaningful swarm before the first turn. The head slot cost is significant since other powerful hats compete for it, but a high-Luck build gets unique value here that nothing else provides.

In dedicated Luck builds, Mangy Wig can become one of the most impactful head armors in the game by late run — 15+ Luck from stacked sources could produce 3 or more Spiderlings every fight. Each Spiderling acts independently, absorbing hits, dealing chip damage, and splitting enemy attention across more targets. Combine with Bird Feed and Colostomy Bag for a full multi-familiar swarm build. Outside of Luck-focused runs, consider Mangy Wig only if you're already passively accumulating Luck from other items.
