Horn Component

Nothing in this list is craftable in turn, so one Horn Component is a single step: 1 unit of material drawn from a single base item, plus 6 crystals.

That is the lightest raw-material bill on the site, tied with 3,129 other recipes, and 9,374 recipes nest deeper.

The single raw material does not appear in the gathering data, so the whole bill comes from vendors, drops or content this site does not track.

Nothing in the data consumes Horn Component: it is one of 112 end products among the 123 Blacksmith recipes at Lv 50.
