Stegadons and Ancient Stegadons have a crew of five Skinks. If taken as a character mount then one of the crew is displaced by the character. Stegadons of both types are treated as monstrous mounts with more than one rider, with the following additional rules.
The crew carry a variety of weapons. For the purposes of the game count these as hand weapons and javelins.
Missile hits and impact hits are randomised as follows: roll a D6. If a character is riding the beast, 1-4 hits the beast, 5 hits the crew, 6 hits the character. If there is no character, 1-4 hits the beast, 5-6 hits the crew.
Skink crew and characters riding a Stegadon have a 3 + armour save, those riding an Ancient Stegadon have a 2+ armour save. These cannot be improved in any way.
When fighting in close combat, attacking models may choose to direct attacks at either a character if one is present, the mount, or the Skink crew. When fighting in a challenge, the character and the mount may fight, while the crew cannot attack at all until the challenge is over.
If the mount is killed, then the Skink crew are killed too as they are crushed beneath the falling body. However, any character may continue to fight on foot if you have a model to represent him. If all the riders are killed, the beast is treated like any other ridden monster that loses its rider. For victory points purposes, only the beast itself counts, unless it is ridden by a character. Non-character Skinks are ignored.
