Introduction of SpritBreaker
An Outcast of the SpiritHoof Clan,Barathrum retreated in shame to the Ethereal Plane feeding off wandering souls to sustain himself, and wandered aimlessly for centuries, alone and miserable. Found and recruited by the Lich King, Barathrum's uncanny speed and wraithlike powers have now been unleashed upon the Material Plane, his lantern able to project nether energy into enemies, sending them backwards with sudden force. With the ability to close the distance between himself and a target in seconds, Barathrum the Spiritbreaker is more than a match for anyone.

[+]Global Stunner
[+]Awesome DPS Attacker
[+]Able to catch Fleeing heroes easily and quickly
[+]High STR Gain
[+]Passive Aura for more MS and DMG

Cons
[-]Single Target Attacks
[-]Lower than average MS
[-]Melee
[-]Charge Of Darkness is unreliable in close range or in clashes

As you can see the pros outnumber the cons and spiritbreaker is also a very fun hero to use and he can acquire some kills after lv 6
SKILLS

Charge Of Darkness
Barathrum takes a few seconds to charge up, then charges at his target , merging with the shadows at high speeds. Upon leaving the shadows, Barathrum shocks his opponent into an immobile state for some time. Enemies can only see the buff indicator when he is near his target.

Empowering Haste
Causes the Spiritbreaker to swing his weapon faster with higher movement speed, allowing him to deal extra damage. His presence increases the movement speed of nearby allied units(Passive)

Greater Bash
Gives a 17% chance to bash enemies across the ground, doing more initial damage and damage as they skid(Passive,Does not stack with Cranium Basher)

Nether Strike
Moves you next to your target doing extra damage. Performs a greater bash hit. Casting range improves per level.

This is my skill build for Barathrum,Spritbreaker for godlike kills,if you disagree with my skill build please place your opinion down i will consider it.Thanks
Item Build
Core Build

That should be it for spritbreaker core,PT's AGi and MoM normally i throw in 2 bracers for extra survivability but that goes under situational items
Extension

An aganims scepter will lower nether strike cooldown to 20 seconds and make it an aoe effect.
Luxuries

Yea thats what i get for my luxuries to me HoT is not really important than assault cuirass.
Situational Items

Bracers normally i get two for extra survivalbility

BKB i see many people use to be beyond godlike i thought maybe this would go under situational.
Rejected items

WOW YOU GET A CRANIUM BASHER WHEN YOU ALREADY HAVE A PASSIVE BASH!!IT DOES NOT STACK WITH YOUR GREATER BASH!!
Finally Strategy
Early Game
lvs 1-6 Stay in your lane and farm as much as you can and faster rush for your core as your core is what you need for a guarantee kill.So don't attack heroes,do not harass heroes,do not aim for first blood unless there is a long disabler partner with you such as DK then there is a chance for a first blood.JUST FARM,LAST HIT CREEPS DENY CREEPS UNTIL LV 6.
Mid Game
You are past lv 6 or at lv 6 and you have your core and your base damage should be quite high.Find a mid life hero or a very paper hero whom is not near and enemy tower and use charge of darkness on that hero.Upon impact,quickly activate MoM and keep attacking the hero just as the stun wears off use your ultimate you should have done a lot of damage.If you aimed a mid life hero the hero shud have died or very red life.and Voila! A kill is made!
Late Game
Farm up your luxuries.And you are probably a god! Do the same as how you will make a kill or if you really tanky u wunt even need charge of darkness you can just ulti the hero and use MoM.

This Concludes my first guide! Hope you enjoyed this guide!If you did not please give me some tips on better ones thanks!
