Magic penetration (Magic PEN) is an attribute that increases the effectiveness of magic damage by ignoring the magic defense of the target by a fixed value or a percentage. Magic penetration starts at 0 but can be obtained through emblems, items, or even hero abilities.

While magic penetration only affects the user's magic damage, Fixed-value magic penetration ignores the target's magic defense below 0 (up to negative 60), causing the magic damage dealt to increase. See the formula below:

$\mathrm {\color {Violet}Total\ Magic\ Defense} =[({\color {Violet}Magic\ DEF}-{\color {Orchid}Magic\ DEF\ Reduction})\times (100\%-{\color {Orchid}Percentage\ Magic\ DEF\ Reduction}-{\color {Orchid}Percentage\ Magic\ PEN})]-{\color {Orchid}Fixed{\text{-}}value\ Magic\ PEN}$
