After MR and other mitigations, 10% of any source of magic damage is further reduced and converted into % ASPD. The buff stacks addictively to each instance applied, and refreshes everytime you receive magic damage.

Let's say Kassadin have 100 MR (50% damage reduction). Some random mage hits Kassadin with a 800 damage nuke, the mage has no Mpen. First, the damage will be halved by MR to 400. After this, further 10% of the damage is reduced (360 damage), and the cut out 40 of damage is converted into 40% attack speed, or a free Recurve Bow.
