Juggernaut - A quick Alt-Tab Guide

Justifications and Reasoning behind item build.

Starting Out:

Items:
Stout Shield - Helps alot against those pesky ranged auto-attacking harrassers and creeps.

Ring of Regen - Passive Regeneration to be made into a Soul Ring. Sufficient Regeneration thanks to the damage block from Stout Shield.

Early Game:

Soul Ring - When used in conjunction with Healing Ward, you and whoever you're laning with will NEVER run out of HP.

Phase Boots - Makes chasing with Blade Fury that much easier with the activateable movement speed boost and the ability to walk right through those annoying creeps.

Core:

Maelstrom - Helps in your farm + the attack speed bonus will help you land a few lucky hits during Omnislash. The icing on the cake is that during your Omnislash, there is also a chance to proc a chain lighting for even more damage.

Aghanim's Scepter - More slashes, lower cooldown. Decent Stats. No reason not to get it with this build's focus being on Omnislash during teamfights.

Late Game:

Mjollnir - More attack speed for more attacks in between omnislashes. The activated ability is also a huge bonus for whoever in your team you want to keep alive. Even if he gets focus fired down, the damage done by the lightning shield would make foes think twice before trying again.
*Note: Never waste the activated ability on yourself. During teamfights, your main aim is to not even be targeted.

Assault Cuirass - The Armour Decrease Aura will make it so much more easier for your team to bash down whatever stands in your way by now, be it towers or heroes. Besides, a little attack speed boost + Armour Bonus never hurt anyone.

Situational:

Black King Bar - For when dem nukes hurt so badly that even Blade Fury and Omnislash doesn't help. Besides, it allows you to run right up and Hit them in the face or position yourself + get a few hits in before using your Omnislash.
