Orks have proven trickier than expected thus far despite the supporting material to work with from Rogue Trader as a base. Again, as I did with the Dark Kin, I've severely nerfed the Orks from the standard presented in Rogue Trader, primarily to put them on a more even playing field with the other races present in the event I should ever choose to run a mixed game.

You may find that some of the penalties that Orks receive are incredibly severe and limit them to a small niche in terms of characteristics, but it does rather reflect Orks in that respect. Much of this is justification for some of the incredible benefits their traits convey.

Stats for Ork equipment can be found by perusing the Only War rulebooks, though I encourage you to remember to subtract the NPC Ork's strength from it's weapon. Other versions of the Ork armoury can also be found in the Rogue Trader rulebooks - most notably "Into The Storm".

Orks are immune to Seduction and Corruption.

Orks are unaffected by Insanity until they reach 100 points, at which point they become a Madboy and are removed from play - often with hilarious and catastrophic results.

Orks must pass a Toughness Test to be affected by human drugs.

In place of human bionics, Orks must opt to use Ork Bionics, which count as Poor or Common Craftmanship versions, should weigh at least twice as much and be covered in crude welds, bolts, pistons and the odd exhaust pipe.

Orks cannot wear Armour sized for other races.

Non-Imperial - Orks suffer a -10 penalty to all Lore tests relating to the Imperium of Man

Speak Not Unto The Alien - Orks count all Fellowship tests as being two steps more difficult when dealing with non-Orks. This can be waived in special circumstances with the GM's discretion.

'Ard - Orks possess Unnatural Toughness 2), Sturdy, Iron Jaw & True Grit. All Medicae tests to treat an Ork's injuries receive a +20 bonus.

Mob Rule - Orks gain +10 Willpower for each Ork within 10m of them for Fear and Pinning tests.

Refer to the Ratling Comrade rules for using Grot comrades.

Tankbusta - The Tankbusta has become adept at hunting his favoured prey on the chaotic and war-torn battlefields of the 41st millennium.

Malpractice (400xp) - Such are the tales of Malpractice and experimental sadism of Mad Doks, that even Orkz are terrified of these Oddboyz, and their malicious glee has an overbearing horror toward other races as well. The Mad Dok gains Fear (1).

Moar! (400xp) - Every time this advance is purchased, the Runtherd gains another Comrade of his chosen type.

Pile-On! (500xp) - The Runtherd bellows at his charges and gives encouraging swipes with his Grot-Prod. He makes a challenging intimidate test, and uses the degrees of success to determine the number of attacks made by his minions. This is a half-action.

Special Comrade - Grots pair up with other Grots, rather than larger Orks.

Advances - Grot Luck, Nuisance

Grot Luck (300 x Grot Luck level, minimum 300) - The Grot gains what is effectively an additional Fate Point per each time this advance is taken, to a maximum of 5. However, these fate points behave as though temporary fate points, and cannot be burned.

Nuisance (xp) - One of the few benefits of being a Grot is that people tend to underestimate you. A Grot may make a Stealth Test during combat to appear as only a minor nuisance in comparison to it's larger kin. This stealth test is opposed by Scrutiny. Should the enemy fail to outdo the Gretchen, he dismisses them as a lesser threat, and instead attacks a larger target nearby.

Nob

Any Non-Grot can become a Nob, with the exception of Weirdboys, but this does not serve as a prerequisite to move into other specialisations.

New Aptitudes - Weapon Skill, Ballistic Skill, Offence, Defence, Leadership, Strength, Intelligence

New Talents - Air of Authority & Heroic Inspiration OR Combat Master

New Traits* - Size Increase, Auto Stabilised, Unnatural Strength (2), Increased Unnatural Toughness to 4.

Specialist Equipment - Nobz retain their specialist equipment from their last non-Nob specialisation.

Advances - Monster, Get Da Boyz!

Monster (400xp) - The Nob increases the value of their Fear rating by 1. If the Nob did not already possess a Fear rating, he gains Fear (1)

Get Da Boyz (400xp) - The Nob adds another Boy to his retinue of comrades. This advance may be taken a number of times equal to the Nob's Natural Strength Bonus.

Nobz may also purchase the Commander specialism's orders.

Big Meks have been scrapped. A "Mekboy Nob" will essentially fulfil the role of Big Mek.

A Deff Dread's weapons are mounted to it's body and must be fitted and removed using a Trade (Armourer) test when a change is desired in loadout.

I love this, can't wait to show my players the "new regiment" they'll be playing as. Imagine their faces when they realize that the commissar screaming in their face (imagination run wild) is actually a nob!
