Bastiladon

An enormous creature covered entirely in impregnable armoured scales, the Bastiladon shrugs off all but the strongest attacks, all the while smashing down enemy lines with all the unstoppable force of a landslide. Stamping down anything able to move out of range of its terrible maw, the Bastiladon’s size means it can be armed with some incredible weaponry. The Solar Engine radiates the staggering power of a sun, casting forth death beams that turn armour to molten slag and incinerate anything alive extremely quickly; daemons are notably vulnerable to this Azyrite light. The Ark of Sotek spits forth a never-ending tangle of serpents, whose star-envenomed fangs bite deep into flesh, causing the blood within to burn with the flames of Azyr.
