Tank item idea - Argo's Artifact

Status buffs:

+300 Health +50% Health Regen +25 armor +25 magic resistance

Passive: 10% CDR Unique Passive: Mitigates all critical damage and percent health damage by 50%

The purpose for this item is to help tanks be tankier during the meta, knowing there is champions like vayne, yi, and yasuo, who are very well acclaimed for destroying tanks, the purpose being high crits, true damage, and percent health damage. This item decreases those factors so the tank champion can be able to withstand some of the pressure inflicted by such enemy champs. For example, Yi is very well known for using bork as a prime item in his build, which helps him a lot against tanks because it deals health based damage and gives him more attack speed to perform it, which gaves tanks a large disadvantage. So with this item, it can decrease the impact of the health based damage, making the tank being able to stand a chance against yi, and the same applies to if yi decides to build crit along with it, so the tank can stand a chance.
