Bitey Bitey is one of Riki's arts in Xenoblade Chronicles. It inflicts Bleed for 10 seconds which deal an additional 20% of the initial damage every 2 seconds. If this art is used from the enemy's back, the Bleed duration is increased to 20 seconds.
Advanced art books are only available from enemy drops. For any enemies listed with a 0% drop rate, the item can only be obtained using Yoink!, Riki's Talent art.
