Magic Damage Up

Magic Damage Up is an offensive buff that increases all magic damage dealt and healing performed by 1 per stack. This applies to spell damage, magical abilities, and healing effects, making it the spellcaster's equivalent of Damage Up. Magic Damage Up is persistent and stacks from multiple sources.

The healing bonus makes Magic Damage Up valuable for healer builds as well as damage dealers. Each stack adds 1 to every spell damage instance and every healing instance, so spells that hit multiple targets or heal multiple allies benefit from the bonus on each individual instance. This makes multi-target spells particularly efficient with Magic Damage Up stacks.

Magic Damage Up pairs well with Double Cast (which duplicates spells for double effect), Intelligence (which improves mana regeneration for more casting), and Magic Weakness on targets (which guarantees critical hits from magic damage). For builds that use both basic attacks and spells, combining Damage Up and Magic Damage Up provides comprehensive damage scaling across all attack types.
