Pros:
-Enemy champions will have difficulty escaping
-Good for escaping enemy champions
-Very forgiving due to his movement speed and shortened death penalty
-Easily takes out waves of minions on his own

Cons:
-Not the best early game
-Doesn't perform as well when enemies have stuns

Vampiric Scepter:
Starting off with this weapon helps to get through early game while you don't have turtle stance.

Berserker's Greaves:
These are useful for their speed boost + attack speed bonus. I recommend them early game because mostly because they are cost efficient.

Wriggle's Lantern:
Once you have this item it means you'll be able to plow through minions and jungle with ease.

Sunfire Cape:
This gives a good a 40 damage aura effect along with some good defensive effects. Be careful though when going through the jungle if you pass by a monster they will be affected by the sunfire cape and attack you.

Frozen Mallet:
A great tanking item, gives a ton of health and slows enemies for 40% of their movement speed. Once you have this enemy champs won't be able to escape you in a fight. On the other hand, if you need to escape and don't have enough mana for bear stance you can attack them once than run away with them slowed.

The Bloodthirster:
You can get this item earlier in the game if you want. It gives great damage with some lifesteal. A good combination if you ask me.

B.F. Sword:
With one slot left, it had to go to this item. Giving a high attack damage boost along with your overall lifesteal percentage.
