Mind Blast is one of Melia's EtherArts in Xenoblade Chronicles. It can only be used when Melia is in Element Burst mode and will remove any auras the targets have activated. It will also inflict Arts Seal on any target.
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.
