[Gameplay] Energizer bug

I played a game as darius, therefore ,without wanting I picked the wrong masteries.

After the first blood with olaf, I noticed I had "energizer" at level 1, thing that helped me out a lot during laning phase.

I thinked to myself: "Well, these masteries must give this buff"; So i decided to check them later.

I got a surprise when I found out when I checked them. Why you wonder? Because there wasn't nothing that provide me the buff.
