Stormvermin are the fighting elite of the Skaven Warlord clans. They are distinguished from their scrawnier litter-matters - often standing a full head taller, with thick muscular necks and a powerful build. Most Stormvermin are marked at birth, as their size and darker fur colour is recognisable. As the largest and most aggressive, young Stormvermin-to-be typically outfight the rest of their litter for precious food. If the young warriors are particularly strong, the weakest of their litter actually become the food. Should they survive the traumatic politics and back-stabbing as their litter-pack jockeys for position, the strongest Skaven will be assigned to regiments of Stormvermin and outfitted with the best war gear. Their duties may include forming a retinue or bodyguard for anyone from a minor Chieftain to the mighty ruling Clan Warlord himself, which puts the Stormvermin at the vanguard of the army where they can ensure continued preferential treatment by fighting with ferocity and zeal for their leaders.
↑Anti-Large: Anti-large units have an advantage against targets that are at least as large as a horse. This advantage can be a damage bonus against large targets or an attack that focuses on a very small area. However, some units are simply better against large targets because their attacks are slow and easy to dodge by skilled melee combatants.
↑Armour-Piercing: The damage of armour-piercing weapons mostly ignores the armour of the target, making them the ideal choice against heavily-armoured enemies. They are often heavier and attack at a slower rate though, making them less efficient against poorly-armoured targets.
↑Armoured: Armoured units can block damage from any source apart from Armour-Piercing damage.
↑Charge Defence Against Large Foes: When standing and bracing against a charge of large enemies (such as cavalry or monsters) this unit will negate the enemy's charge bonus.
Stormvermin perform much better in a fight than Clanrats, but are quite costly in comparison. Often times, better value is gained from multiple units of Clanrats than a single Stormvermin unit. However, their armor-piercing damage can make them good line infantry against Chaos, Dwarves, and especially Lizardmen, with their large number of heavily armored monster units. In the campaign, they are effective "endgame" infantry when cost becomes irrelevant, but Clanrats should form the bulk of your armies. If possible, keep only a few units of Stormvermin to guard important units such as the Lord or Heroes, or keep them on the flanks. Their melee stats are sub-par compared to other race's elite infantry, but they maintain the 160 model unit size that Clanrats have while other elite infantry will generally only have between 80 and 120 models. They are generally preferable to their sword and shield wielding counter parts as they do a decent job holding back infantry, have good AP damage, and the bigger threat to your lines is generally large units smashing through them.
