All types of kalau are expert trackers and hunters. They can follow a trail with a base 80% chance of success.
The breath of the earth kala causes disease in all who fail to make a saving throw vs. death. This breath has a range of five feet and a width of two feet. The disease slowly weakens the victim, causing the loss of 1d6 hit points per day. While so diseased, the victim cannot heal or benefit from the effects of magical healing.

Does the disease breath sound like a normal or supernatural disease? I can read it both ways.
