[HERO] Ork Warboss

Some dark power certainly favoured Ghazghkull Mag Uruk Thraka, for his rise to power among the tribes of Urk was meteoric. He fought his way through the ranks until he achieved the position of supreme planetary Warlord. Orks respect strength, courage, and battle prowess, and it could not be denied that Ghazghkull possessed all of these qualities in abundance. In addition, he had something that most Warlords lack: vision. He stirred the Orks of his home world with impassioned speeches telling them how it was their mission to conquer the galaxy. Wherever Ghazghkull went, he united warring tribes with an overwhelming sense of destiny.

"With his trophy rack full of enemy heads of all kinds, Thraka has proven his true value in battle to all orks around him. After all, he is the warboss."

Whenever Thraka kills an enemy, he gains 1/2/2/3/3/4 WAAAGH! counters.
Each WAAAGH! counter gives him 5 damage, to a max of .5/.55/.6/.65/.7/.75xStr
Each counter also gives him a 1% ias and 0.2% ms aura.
WAAAGH! counters last for 20/25/30/35/40/45 seconds, with a max of 100 WAAAGH! counters.
aoe: 800

"Being headbutted by Ghazghkull is much like being hit by a mag-train. Any unit on the receiving end of one will be sent flying."
Deals damage equal to 75 + 1/1.25/1.5/1.75xStr and 1/2/3/4x armor, stunning the target for 1.25/1.5/2.25/2.75 seconds.
The target is knocked back 1/2/3/4xStr distance.

"After an incedent involving a bolter shell, Thraka's head, and Mad Dok Grotsnik, Ghazgkull claimed to be in direct contact with the Ork gods Gork and Mork."
Thraka is able to call uppon the powers of Gork or the powers of Mork in battle.
While either power is activated, each attack will cost 2/2/1/1 WAAAGH! counters.
If Thraka kills a unit while these powers are activated, the effects will double for 10/12/14/16 seconds.
If the killed unit is a hero, he gains additional effects.

Spoiler:

Powers of Gork:
"To the Orks, Gork is brutal but kunnin', and in the cosmic duals between Gods, Gork grins, bears his long teeth, and lands a might blow on his adversary's head with a spiked club the size of a comet."
On each attack, Thrakka will recover 6/8/10/12 hp at the cost of 2/2/1/1 WAAAGH! counters.
If he kills a unit, the bonus will double. If he kills a hero, his attacks will also reduce his targets armor by 4.5/6/7.5/9
Additional effects last 10/12/14/16 seconds.

Spoiler:

Powers of Mork:
"To the Orks, Gork is kunnin' but brutal, and in the cosmic duals between Gods, Mork, the master of cunning, waits untill his foe isn't looking before clobbering him with a low blow."
On each attack, Thrakka will recover 3/4/5/6 mana at the cost of 2/2/1/1 WAAAGH! counters.
If he kills a unit, the bonus will double. If he kills a hero, his attacks will also reduce his targets magic resistance by 5/10/15/20%
Additional effects last 10/12/14/16 seconds.

Leader of the Green Tide

Basically a damage reduction, passive, dependent on number of units around him. Add other unique effects as you will.

"Ghazghukll is a mighty prophet of the WAAAGH!, captable of rousing entire planetary populations of Orks into a frenzy of conquest and bloodshed. He is the single most infulential Ork in the galaxy, and billions of greenskins march to war in his name."
Gives all nearby allies 30% movement speed for 6/8/10 seconds.
The first attack by a unit with this buff will remove the buff, give it a 2/2.5/3x critical hit for that attack, knockback the target, and give it 20/40/60% ias for 8 seconds.
If a unit with the attack speed buff kills an enemy, it gains the initial movement speed buff again.
aoe: 800, manacost: 175/225/275, cooldown: 120/100/80 seconds.

Spoiler:

not complete yet... just have an ult and know that we're basing it off ghazgul.

Someone should translate the titles of the skills to Orkish, though.

Prophet of Mork and Gork (innate)

Toggles between blessings of Mork and blessings of Gork.
Inactive --> Mork --> Gork --> Inactive. (if you can figure out a way to do this differently, that'd be nice. You'll see why it'll be inactive.)

Blessings of Mork gives 1/2/3/4/5/6 mana back on hit, while Blessings of Gork gives 2/4/6/8/10/12 health back on hit. For every second a Blessing is on, 6/5/4/3/2/1 Waaagh counters are used.

When killing a unit with a particular blessing on, the bonuses are doubled. If having killed a hero with a particular blessing on, additional bonuses are granted for 4/6/8/10/12/14 seconds:

1. 
   Blessing of Mork will bestow the ability to reduce the magic resistance of the unit attacked by 0.5/1/1.5/2/2.5/3% per attack, with a maximum reduced percentage equal to 50% of Ghazghkull's intelligence.
   
2. Blessing of Gork will bestow the ability to then reduce physical damage resistance of said unit by 1/2/3/4/5/6%, with a maximum reduced percentage equal to 50% of Ghazghkull's agility.
   

Trophy Rack: With his trophy rack full of enemy heads of all kinds, Thraka has proven his true value in battle to all orks around him. After all, he is the warboss.

For every kill Thraka gets, he adds 5 damage across all levels for each kill, with a maximum amount of damage no higher than 50/60/70/80% of Ghazghkull's strength. Additionally, he gains 5% attack speed, and 1% movement speed per kill and disperses it as an aura. Attack speed and movement speed caps out at 100% attack speed and 20% movement speed. Fades over 15/20/25/30 seconds.

Headcrusher (Translate to Orkish, plox)
Basically, Thraka can use his Adamantine skull to deliver the most awesome headbutt ever seen among the orks. Grots say that they once saw Thraka and a Squiggoth go up against each other and Thraka blew it back with his head. Then again, they are grots. >> [Just a general fluff, still needs to be orkified]

In melee range, Thraka slams his head against an unlucky foe, stunning them and sending them flying for quite a distance. Does damage depending on Thraka's (Strength Armor value) x 1/2/3/4 and sends the enemy unit back 100/150/200/250 distance, stunning them for 1.25/1.5/1.75/2 seconds at all levels.

By the way, waaagh counters will appear in a new skill. They'll determine either the potency or the duration of his skills or both. They'll be gotten simply by fighting and killing things. xD
