Rizzrak Goblin Shredder Item Build

The new map for DOTA, 6.73b, which fixed some bugs on 6.73, featured four new additional heroes.  Xin Ember Spirit, Dragonus, Skywrath Mage, Tresdin, Legion Commander, and my favorite, Rizzrak Goblin Shredder.

So what would be my Rizzrak Goblin Shredder Item Build?

First, we need to know the skills of Rizzrak Goblin Shredder. According to playdota.com, the following are the skills of Rizzrak Goblin Shredder:

Whirling Death
================
(Active, no target)
Goblin Shredder whirls extremely sharp edges dealing damage and reducing primary attribute of any unfortunate enemy hero who comes in a 300 AOE around him. Deals Pure damage if it cuts down trees in the process. Lowers primary attribute by 15% for 7 seconds.
Damage: 100/150/200/250
Manacost: 70/80/90/100
Cooldown: 8

Notes:
Whirling Death deals magical damage by default. If it cuts down trees as well, it becomes pure damage.
Ability Code: A2FK

Timber Chain
==============
(Active, targeted point)
Fires a chain that embeds itself in the first tree it hits, pulling you to it and cutting any enemy in your path for pure damage.
Damage AoE: 225
Range: 800/1000/1200/1400
Damage: 80/120/160/200
Cooldown: 4 seconds
Manacost: 60/70/80/90
Note: You will not be pulled in if you are stunned when the chain latches onto a tree
Ability Code: A2E3

Reactive Armor
================
(Passive)
What doesn't kill ya makes ya stronger! Every physical attack made on Rizzrak increases his armor and gives him bonus hp regen. Each stack lasts for 16 seconds.
Bonus: 1 armor and 1 HP regen per stack
Stack Limit: 4/8/12/16
Ability Code: A2E4

Chakram
=========
(Activatable, targeted point)
Fires your main saw blade at the target location, and once there the blade will spin, dealing damage in an AoE around it and slowing enemies by 5% for every 5% of health they are missing. The blade deals pure damage and cuts down trees in its path when fired and retracted. You lose the ability to attack while the blade is out.
Passthrough Damage: 100/140/180
DPS: 50/75/100
Cast Range: 1200
Manacost: 125/150/175
Manacost per second: 20/30/40
Cooldown: 8
Notes:
Chakram returns to you if you go more than 2000 units away. Destroys trees.

As you can see, the cooldown of his skills are so small, that you can spam it to your opponents.  Also, as you may notice in the third skill, which is a passive skill, his armor increases as he is being attacked physically, which makes him more of a tank.

I am not a professional DOTA player but I guess my item build for Rizzrak The Goblin Shredder is a good one.  Here is my Rizzrak Goblin Shredder Item Build:

Empty Bottle & Courier
At first, you need a good source of mana to be able to spam and farm some gold.

Boots -> Arcane Boots
Farming is easy if you have a good mana regen. I immediately go for arcane boots after farming some gold for immediate mana regen.

Perseverance -> Linken Sphere
You will be the tank of your team as you go to clashes, and Linken Sphere is a good item as your opponents may cast spells on you.  This would help disable such spells.

Perseverance -> Bloodstone
With the combination of Linken Sphere and Bloodstone, you no longer worry about mana regen and you may use your Chakram anytime you want.

Alternative items:
Orchid Malevolence
Guinsoo's Scythe of Vyse
Eul's Scepter
Rod of Atos
Radiance

So that is my Rizzrak Goblin Shredder Item Build.  :)
