[GAMEPLAY] "Sorcery" mastery is increasing autoattack damage

The Sorcery mastery is amplifying the physical autoattack damage component of Cho'Gath's Vorpal Spikes, when it really shouldn't be. The video shows the proof. I know it is the Sorcery mastery because I kept trying different masteries until I found the one that made this bug happen. With Sorcery, this bug happens; without it, the bug does not happen.
