Module:Variants

Creates a section containing all items with the same Variant property, ordered by the sum of the profession level requirements in ascending order.

If a variant does not have a profession level, 0 is used as a fallback, meaning items with unknown level requirements will always appear first in the list.

Usage:

{{Variants|Eel}}

Result:

Lesser • Gray • Rocky • Rord • Moray • Conger • Leopard • Greater
