Can Cause Fear: This unit frightens all enemy units, reducing their leadership when nearby. It is also immune to fear. Fear penalties do not stack.
Vanguard Deployment: This unit can deploy outside the deployment zone.
Hide (forest): This unit can hide in forests until enemy units get too close.
Moon-howlers (Goblin Wolf Riders) is a Greenskins cavalry unit. With a pining cry to the great, weird moon, Morrslieb, these wolves carry their Goblin riders to war.
The Moon Howlerz or Moonhowlaz were a tribe of Goblins from the Dark Lands
During the early End Times, this Wolf Rider tribe joined the Moonclaws, acting as the eyes and ears of Grulsik Moonclaw. They were led by Grak Mankfur, the Goblin wolflord, who rode beside the prophet of Mork, Shekka Fangtoof – a flea-bitten but powerful Goblin Shaman. The bulk of the troops were divided among the Blacktailz mob and Gray's Dogboyz.
↑Shielded: Shields have a chance of blocking arrows, bolts, rifle shots and similar small arms fire - but only in a forward facing arc.
↑Very Fast: This unit can run circles around most other units, taunting and harrassing the enemy or evading its missile fire.
The intended benefit of this Regiment of Renown is that they cause fear (which also makes them immune to fear notably). This is helpful, but nothing incredible. One of the real benefits is their higher leadership (+10) and melee stats (+7 for both defence and attack) which puts them into an incredibly fast light cavalry with decent melee stats and tolerable leadership.
