To hold the title of Warlord is to rule. A Skaven does not gradually earn respect or position, and there certainly is no giving in the brutal society of the ratmen. Leadership must be savagely taken. To gain power, a Warlord must seize control, proving himself a top fighter and a devious adversary. Such a coup either ends in failure and certain death at the hands of the existing ruler, or the new leader supplants the current Warlord, often eating him in the process. Challenges follow no format but often take the form of personal combat, treacherous back-stabbing, or elaborate political schemes. The more underhanded the deed, the better, for that is what puts the fear (and what almost passes for respect) into the Skaven masses.
↑Armoured & Shielded: Armoured units can block damage from any source apart from Armour-Piercing damage. Shields have a chance of blocking arrows, bolts, rifle shots and similar small arms fire - but only in a forward facing arc.
Putting him on a Bonebreaker grants him Siege Attacker, Cause Fear and Frenzy. It will also be considered a Moulder Monster. It will also make the Warlord an Armour-Piercing beast of a fighter. However, the Warlord will lose his shield.
