Eschuta's Temper is a unique Eldritch Orb, an item exclusive to the Sorceress. With a more consistent boost to Sorceress skills and a high magic find, The Oculus may seem like a safer choice for a unique sorceress weapon. However, Sorceresses that specialize in Fire Spells or Lightning Spells may find Eschuta's Temper more useful. Because the bonus damage stacks with the masteries, Eschuta's Temper only adds anywhere from 1-12% of extra damage - not the 20% that is stated on the item - the Heart of the Oak may be superior with its extra resists and mana instead.
