*raises hand up*<br/><br/>I detect creatures of darkness and I think that sensor does not give any damn about someone being half-breed. It would detect any creature of darkness, may it be half or full so long they do possess the subtype to be classified as such (meaning creature of darkness applies to any 'dark monsters' or someone with dark powers or having dark blood in their veins). Altough universal as it is and able even back trace it to somewhat ID what sort dark creature is in close radius but it is vague in long distances. Only up to 10'ft my char would able say 'you!' and able determine exact location.
