Justicar Mask isn’t something you “craft” in Deepwoken; the closest relevant item I found is Justicar’s Armor , which needs 5 Cloth, 5 Fiber, 1 Wayward Gem, 5 Gale Stones, 4 Thresher Spines, and 1 Dark Feather , and it also requires Power 15 to craft.

What that means

  • If you meant the Justicar outfit/armor , those are the materials and requirement.
  • If you meant an actual mask , the Deepwoken mask page confirms masks are a separate face-equipment category, but the search results I found did not show a specific craftable “Justicar Mask” recipe.

Best next step

  • Check whether you mean:
    • Justicar’s Armor , or
    • a mask cosmetic tied to the Justicar Origin.

TL;DR: I could verify the crafting recipe for Justicar’s Armor , but not a distinct Justicar Mask recipe.
