" Xerath is good at ignoring magic resistance with  Void Staff and  Arcane Knowledge, while  Locus of Power is activated. That&apos;s 67.6% Magic penetration ." The fiorst part is true. Xerath IS good at ignoring magic resistance. So good that he wastes his money on a void staff. Here are the 2 things are wrong with the wiki statement: 1. % based magec penetration stacks additively, meaning that the real number would be 90% with maxed Locus of P ower; and 2. the main issue is that % based magic penetration caps out at 46%. If you don&apos;t believe me go into a game, with all 3 of the % magic penetration sources listed above, click on your character protrait, and look at you magic penetration stat. You will see a wonderful 46% glaring at you. Xerath can attain this cap without any items so do not buy void staff on him EVER.
