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.
Hide (forest): This unit can hide in forests until enemy units get too close.
Cold One Spear-Riders is a Lizardmen cavalry unit in Total War: Warhammer II. A pack of Cold Ones, ridden with skill, can charge powerfully into melee and remain there for some time.
Saurus warriors are formidable fighters, but when mounted atop a Cold One they become a shock force capable of delivering an absolute mauling. Those foes who can muster the courage to stand before the sight of oncoming Cold One cavalry find themselves beset by a whirlwind of biting jaws, slashing talons and jabbing spear thrusts. Those Saurus Warriors blessed by Itzl have an innate aptitude for mounted warfare. They exude a musk not dissimilar to the rank odour produced by the Cold Ones themselves, allowing them to form bonds with the otherwise hostile creatures. The Saurus have dewclaws that are perfect for gripping the thick-scaled hides of their reptilian steed, leaving them free to carry both spears and shields. All such spawning produce a Pack Leader who instinctively leads the group - knowing where to find the Cold Ones and how best to break them in as mounts.
↑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 & 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.
↑Predatory Senses: These units are natural hunters that can sense prey hiding nearby.
There are two possible solutions to enemy cavalry flanking as Lizardmen. The hard way is to play a game of chicken with your Saurus Spears and the enemy, constantly micromanaging and adjusting your flank and daring them to throw themselves on your obsidian spear points. The easy way is to throw some Spear Riders at them and be done with it. Cold One Spear Riders are only above average anti-large cavalry, but even if they lose the engagement, they'll do a lot of damage to the enemy and whatever comes out of the ensuing meat grinder is a much reduced threat.
