Volibear is a very strong laner. Expect him to play aggressive in attempts to get an early lead over you.
Once Volibear is level 6, avoid staying in lane when low as he can use his Ultimate R aggressively and catch you out. If you are forced to recall, do not recall under tower as his Ultimate R can stop towers dealing damage.
Stay at max range at all times and retreat briefly if he activates his Q. Staying at max range when you’re not looking to trade will make laning against him much easier.
Buy items that provide Grevious Wounds like Executioner’s Calling or Morellonomicon. This will prevent him from healing and surviving team fights.
In team fights, avoid grouping too closely as it will allow Volibear to get a great Ultimate R off. Group, but do not stand too close together.
Volibear has great pick potential in the mid-game. Avoid going in unwarded parts of the map if you know Volibear is in the vicinity.
Once Volibear hits level 3, he can look for a favourable trade when all 3 of his basic abilities are up. Expect him to play aggressively at this time.
At level 6 and whenever he has his Ultimate R up, you need to play more cautiously and avoid committing to fights when you’re low. In particular, recall if you’re low, under tower and when he has his Ultimate R available.
Once Volibear has completed his first item, his damage output increases a lot. Expect him to play more aggressive and look for kills.
