The Arthana is a weapon added by Witchery. This weapon inflicts 4 () points of damage per hit and is used to increase drop rates for animal drops such as the Wool of Bat, Tongue of Dog, etc. Without the CoFH Core mod, this tool is the only way to obtain Skeleton Skulls, which are key for upgrading the Altar with Alluring Skulls. It also increases drop rates and allows other heads to drop, such as those of players and Zombies. It does not change the drop rate for Wither Heads. Some Circle Magic will require the Arthana as a foci, but it will not be consumed during the ritual. This tool can be repaired with Golden Ingots.
When placed on an Altar, it will double its power distribution range.
