[Gameplay] Morderkaiser with the 10% bonus from Revitalize
Revitalize's 10% stacks different than the 5% one. That's because the first one is heal and shield power and stacks additively with other heal and shield power. The 10% instead stacks multiplicatively with it (like Spirit Visage), but unlike spirit visage it also increases the power of shields.
Thing is, it doesn't increase the shield power of Morderkaiser's passive. Heal and shield power does increase it (and the 5% part of Revitalize), but the 10% one doesn't, and it should since that's what it says in the description.
