Stone Trolls

Stone Trolls are a Greenskins monstrous infantry unit introduced in The Warden and the Paunch.

Description
Stone Trolls are a distinct breed of Troll which live exclusively in caves and mountainous regions of the world, hence their name. Since they live on rocky mountains, they tend to consume large quantities of stone and rock, the natural magical inertia of the stone imbues them with a certain degree of magical resistance.

Attributes

 * ↓ Poor Leadership: This unit suffers from poor leadership and will easily rout. Keep its flanks secure and your Lord or other encouraging units nearby.
 * ↑ Regeneration: Regeneration allows a unit to heal while in battle. Fire is known to harm this healing process, so be warned that flaming attacks will cause more damage to units with Regeneration.
 * ↑ Scaly Skin: Scaly skin or hides help to dampen or deflect the damage caused by missile weapons, increasing this unit's Missile Resistance.
 * ↑ 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.

Strategy
Essentially normal trolls with a slight boost to armour piercing as well as some magic and missile resistance. This allows the player to bring a tankier and more resistant troll at a higher cost.
