Runtherd
Hey! You ever wondered where all the Gretchin get all their 'motivation' in a battlefield from? You ever wonder how a Grot is able to take pot shots from locations too strategic and complex for their shallow little minds? Look no further than an Ork with a prod stick and you get yourself a Runtherd (Or Slaverz).
Overview
Runtherds are Ork Oddboyz who have the patience to take care of are responsible for exploiting Gretchin and Snotlings. Far from detesting their jobs, Runtherds often take pride in their jobs and like any good breeder will try to produce the fiercest Grots and Snots they can (not too fierce though, a Grot should know 'is place). Also, they take full credit for any brew of fungus beer crafted by Gretchin and their rabble.
Their characteristic weapons are whips, Grabba Stikks and Grot-prods, the latter of which are tazer-like weapons created by Meks. While Grots are marginally effective in combat they are nevertheless useful as living bullet-catchers, so Runtherds are often seen leading large Gretchin mobs into the fray or ordering around the Gretchin crews of Big Gunz. Runtherds often make use of Squig-hounds to eat errant or fleeing Grots in battle to "increase" the morale of their Gretchin mob.
A Runtherd will sometimes work with a Big Mek to goad Snotlings into the maw of a Shokk Attack Gun so that the Mekboyz can use them as living ammunition. If a Mek is not around, than the Runtherd will 'convince' the Snotlings to attack the nearest enemy with whatever they have via pain of death. Usually the Snotlings fail to even tickle the enemy and end up mulched whilst the Runtherd laughs his green ass off.
Equipment
As you should already know, Runtherd are armed with three distinct and useful tools/weapons. The first is the Grotwhip, which is basically a barbed lash several metres long used by Runtherds to keep Grotz in line. The second is the Grabba Stikk which are the traditional tool used for throttling anything in arm's reach. Consisting of a sturdy metal pole, a deceptively simple pulley system, and an articulated barbed claw, Grabba Stikks are used to capture and restrain potential slaves. In battle, Runtherds often use them to throttle enemies within the weapon's reach. The third and final one is the Grot-Prod constructed in a deal with the local Meks to deliver a short, sharp shock to an errant Grot's vulnerable parts. These electric prods can also made into a formidable close combat weapons by increasing the voltage to lethal levels.
