Damage Reduction
Damage Reduction refers to abilities and items that reduce damage taken by a percentage. All sources of damage modifiers are applied after mitigation from Armor and Magic Armor are calculated. Unless stated otherwise, True Damage is affected by these modifiers. Direct Health removal, however, is not affected.

Pseudo-reduction
While these sources instantly heal back a portion of damage taken, it does not prevent lethal damage and is affected by reduced healing effects (i.e. Mors Certissima and The Undying).
