The Relentless Storm is a great way of baiting enemies to overcommit in a fight to kill you. It heals a lot in a fairly short amount of time. However, note that it is less effective against burst damage.

Thundering Smash also gives a stack of Frenzy . If you're at two stacks, use Thundering Smash to throw the enemy behind you and go in for the kill with Frenzy . its high cooldown, it's better to use it to finish off an enemy rather than initiating with it, since it scales better later in the fight.

Flinging an enemy with Thundering Smash and then activating Sky Splitter makes it difficult for enemies to run from you, giving you an opportunity to drop their health down with normal attacks and finish them off with Frenzy .

Sky Splitter can be used to differentiate a champion from its copy, in the case of Mirror Image or Hallucinate, as it will slow the champion but fear the copy.

Spirit Visage synergizes very well with your passive The Relentless Storm allowing you to heal for a lot more over the duration.

Since only two of his skills scale off AP, Volibear is free to diversify into tankier items.

The base damage on Stormbringer is high enough that building attack speed is better and cheaper than AP if you want to maximize damage for that skill. Doubling the damage would take 250 AP at rank 1, and 516 AP at rank 3; a 100% AS increase only takes two items, and far less gold.

Frozen Mallet is thus preferable over Rylai's Crystal Scepter for slowing enemies.
Volibear can perform well with an off tank build.

You only need to place two wards on this map, one by Grez the Lizard and one in front of the Dragon so you can see when people are going to gank and when people are going to jungle; making them targets for ganking.

Sight wards are best despite the fact that Vision Wards can detect other wards because they're simply much more cost effective. However, if you have some extra cash buy more wards and put them in front of the creeps, it's a slightly overkill but will make for better map control and more precise ganking.

Wolves

Buff: Crest of Nature's Fury

Increases attack speed by 20% and reduces cooldowns by 10%

These ancient and feral creatures are to be feared, killing them gives you an additional 20% attack speed and reduced cooldown. This buff is brilliant for most characters but you really notice the difference on ranged and melee DPS champions.


Wraith

Buff: Crest of Flowing Water

Increases Move Speed by 30%

The wraith are legendary creatures to be found all over runeterra, however the ones on the Twisted Treeline are far more sinister and superior to there counterparts, as such they bestow a gift of additional speed to the one strong enough to slay them. Great for assassin type heroes or any who dare to challenge them.


Lizard

Buff: Blessing of the Lizard Elder

This unit's physical attacks slow the target's movement speed by (10/20/30)% (at levels 1/6/11) and deal (7.7 + Level * 2.35) true damage based on their level. If the buff holder is slain, this buff is transferred to the killer.

Ah yes, the Elder Lizard, also known as "Grez", this bad boy is a relative of the ones found on Summoner's Rift and happens to go to a tea party to catch up with all his relatives every week, that is unless a challenger, or three, appear to kill him and take the mighty red buff from him. On this map the red buff can change the flow of a game in an instant; therefore it's best to save it for your main damage dealer.


Dragon

Buff: Crest of Crushing Wrath

This unit deals <Champion Level>% increased damageLast, but certainly not least, the dragon.

This bad boy is like the Baron Nashor of Twisted Treeline and has dominion over this area; any seeking his permission to pass must fight him, and if they defeat him he will bestow them with the mighty gift of an additional 18% damage and 150 gold to your entire team. However, do not underestimate him. At low levels it's best if all 3 of your team are there to take him on.
