The dragons will start with a red pearl on top of the head tile and this pearl will eventually end up moving to the final segment of the Dragon, which will have to immediately take one damage.

The clouds will strategically be used to stop the movement of the pearl for a while and avoid damage.

Once the dragon reaches only two segments, the red pearl will be placed on the fire track of the corresponding dragon, which can be used to make an attack of 4 damage by using a fire attack.
