The mastery** "Piercing Thoughts" **gives 7% Magic Penetration The Void Staff item 3135 gives 35% Magic Penetration But if you buy the Void Staff when you have the Mastery, you will not get 42% as you should get, you will **just get 40% Magic Penetration **

7% + 35% is not 40% as it gives now 7% + 35 % is 42% as it should be

This is not a bug. Percentage penetration does not stack additively, it stacks multiplicatively. The formula for it is:

1 - [(1 - .35) * (1 - .07)]

which comes out to .3955, or 39.55% which the game rounds to 40%.
