yes, currently that makes no sense. What do you mean by "18 magic resistance Makes the MR boost. 1.18x"?

If you have 20 mr you've got 16.6% damage reduction

If you have 38 mr you've got 27.5% damage reduction

Buying 18 magic penetration will give you exactly 15% damage increase

Instead. If you have 300 armor you've got 75% damage reduction. If you have 318 armor you've got 76% damage reduction.

Buying 18 magic penetration will give you a 4.5% damage increase
