Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
G'day, bronze 3 here. I know it doesn't give much creditation, but i'm pretty sure i'm the only person in all of OCE with a level 5 mastery on Bard, so do what you want with that. Now, you might notice something with this build. Most of these items give on-hit effects. Bard loves this, he just sits at the back of a teamfight throwing his meeps (or penguins) at the enemy and dealing tons of damage to them all.
Why these items?
Now, if any of you out there didn't know, bard technically has 2 autos in one thanks to his meep's. this means stacking the Guinsoo's passive is easy. Plus even after all of your meep's are consumed, you're still shredding through the enemy's health. Vayne has nothing on this
Why should I listen to you? a stranger on the internet?
Because it's playing bard. You can't go wrong with bard.
