The Old Grumblers

The Old Grumblers is a Dwarf ability innate on The Grumbling Guard (Longbeards - Great Weapons).

Age, beard-length, and the courage that binds them; motivation, if any were needed, to fight on to the end.

Effect

 * Type: Augment (Area)
 * Duration: 5 Seconds
 * Cooldown: 25 Seconds
 * Targets: Self, affects allies in range
 * Effect Range: 40m
 * +9% Vigour

Strategy
9% Vigour may not sound like a lot, but given that a Dwarf army is generally made to endure their foes and grind them down over a long period of time, this ability is helpful for keeping them in the best fighting shape. Even bumping a unit from Exhausted to Very tired is a significant boon. On top of that, the cooldown is very short so this ability can be spammed easily.
