Ty a lot dude!! About the mastery thing, I have tried it sometimes, but I still stick to the flat MPen ones (as above, I use them when I wanna empower voidlings's power)
About the BBCode, thanks, but I still wanna improve on it, it is my first guide so it's pretty good in my opinion!

I'm currently planning to add more counterpicks and matches, when I have more time to do it

Thanks for your comment and for reading!

Besides the above ^ the guide is pretty good and has decent use of BBcode.

Hi, thanks very much for your comment, I hadn't noticed the Moonflair Spellblade thing so oops!
I will edit that. Thing is, that i still prefer the pure MPen mark because it gives you more penetration, only use the hybrid ones when I want to empower my voilings. However i'll put a note ;)

What did you think of the rest of the guide??

Greater mark of hybrid penetration is way better, early game you could poke hard with your basic attacks, especially verses melee champions, and your voidlings deal physical damage.

Edit: Moonflair Spellblade doesn't exist in summoner's Rift. So watch out for that.
