An Arthana is a ritualistic knife use by witches and warlocks to both collect special ingredients and to perform some rites. It has the same general properties as a golden sword (damage, enchantability, etc.), although it has the durability of an iron sword. It is repaired with a Gold Ingot.

The main purpose of the dagger is to collect specialist ingredients used in witchcraft, and to this end it will dramatically improve the chance of a mob dropping such ingredients (e.g. Wool of Bat, Tongue of Dog, etc.). It also gives a small chance of undead dropping Spectral Dust.

When only using vanilla Minecraft with Witchery (and no other mods), an Arthana dagger is the only way to get a skull to drop when a skeleton is killed, the drop chance is about 5% (the skull is a key upgrade for an altar). The dagger even gives a very small probability for other head drops (from mobs and players). All drop chances are increased with the Looting enchantment.

An Arthana does not change the drop chance for Wither Skeleton Skulls, that will require the Looting enchantment as usual.

Some Circle Magic rites use an Arthana as a foci, the Arthana is not consumed in the process.

An Arthana is crafted using a Gold Ingot, Gold Nuggets, an Emerald and a Stick.
