Notes
- Spirit Visage's passive will increase self-healing (in this case, spell vamp) by 25% multiplicatively. For example, it will modify 20% spell vamp to 25% spell vamp (20% × 1.25 = 25%).
- Spell vamp applies to all damage types and will benefit from any damage that triggers spell effects, which is usually sourced from abilities and item actives.
- Proc damage ( on-hit damage, e.g. Bio-Arcane Barrage, Wuju Style, Wit's End), default damage (e.g. Queen's Wrath, The Relentless Storm, Umbra Blades), and basic damage (damage dealt by raw basic attacks) do not trigger spell effects and thus do not benefit from sources of spell vamp.
- Damage dealt by area of effects benefit from a third of the vamp acquired.
- Although some abilities may be single-targeted, that does not mean they never deal area damage; Conflagration deals area of effect damage to all enemies, despite targeting only one unit.
- Abilities such as Lay Waste and Obliterate that deal modified damage based on the number of enemies hit will deal spell damage if only one target is hit and area damage if multiple targets are hit. The former benefiting from vamp at 100% effectiveness and the latter benefiting from vamp at 33% effectiveness.
- Although some abilities may be single-targeted, that does not mean they never deal
- Persistent damage (e.g. Blaze, Malefic Visions, and Dream-Laden Bough) will benefit from vamp at 100% effectiveness.
- Reactive damage (damage type exclusively used by Bramble Vest and Thornmail) will not benefit from vamp.
- Grievous Wounds will reduce the healing received from all sources of vamp.
