The Elementalist, Catalyse and Light of Divinity clusters have been merged into one unholy cluster. Small Spell Damage and Weapon Elemental Damage passives have been replaced with Elemental Damage passives.
Elementalist has been renamed Holy Dominion. In addition to +12% to all Elemental Resistances, 5% chance to Freeze, Shock and Ignite, and 12% increased Elemental Damage (up from 10%), it now grants 12% increased Global Physical Damage.
