A special trait that can't be passed on. Mounts override the movement of smaller characters on certain biomes on the Overworld.
For example, a small sized character with normal movement, who is unable to cross a lava tile, can ride a normal sized Lava Mount to cross a lava tile. An equally normal sized character with normal movement does not benefit. Lava Mounts additionally grant lava portal access, even to same sized units.
Can be acquired by a Mount unit with the Heat Resistant trait.
