Let me TELL YOU A SECRET (That i am somewhat afraid to tell)!!!! :)
I am a Volibear main and this is my secret op build. Im probably risking him getting nerfed by telling you this secret.
I see people going full tank on him all the time. While that is effective in some situations, in MOST situations its better to build him as a fighter that he is classified as. Keep in mind, Volibear is an EXCELLENT DUALIST. So please don't just tunnel vision into his W damage.
Keep in mind build order depends on situation and enemy team but generally when I play **volibear top **and im doing fairly well this is my build order:
Belt - Stinger - boots - Zephyr - Omen shield - Spirt Visage - Ninja Tabi - Frozen Mallet - and final item will be either more atk speed Triforce, Maw of Malmordius for damage and mr, or Thornmail depending on enemy and my team.
I chose zephyr first over triforce cuz it gives you tenancy/CD BUT MOST IMPORTANTLY it is $1000 dollars cheaper while being just as effective and this means you can start being tankier $1000 faster!
Volibear's main damage source is actually his atk speed and his W, not just W. Give that build a try. You will be SURPRISED at how Fast/maneuverable and insane damage output he will produce. I don't usually see people build him this way. Now I have given out how secretly op he is. He is a good top lanner try him out! Im probably risking him getting nerfed and could be a mistake to post this forum.
This isn't my main account. In my main I am ranked top 14% and climbing. Not the best rank but its just to tell u that im not just a silver 4 noob giving noob suggestions. :)
