- Murderous rage is activated either at hearthfire (or perhaps ancestral shrine), this prevents the player from popping it in an instant and on a whim to murder an unsuspecting sprucecap, and enjoying the knock-out protection right up until the fact.
- Murderous rage has a few chances an hour to drop a special short-lasting scent. Each scent is either visible, or not, to any hearthling, and the odds are influenced by a comparison of detector's vs. owner's psyche values. Intuition is imprecise.
- The owner doesn't see his own scents.
- The scent's function is to serve as a vague sort of a warning, a heads up, a hunch, an eerie feeling, a smell of blood on the air, but not much more. Unlike most scents, it shouldn't give accurate information of where the owner might be, but potentially, and depending on examiner's psyche, it could:
>say how recent it is
>give a very imprecise tracking pie pointing in the direction of the owner (think 180 degrees). Psyche could once gain play a role, and perhaps character with extremely high values in the stat could enjoy somewhat higher precision, but heavy investment would be required before one could become a PSYCHIC DETECTIVE.
>allow to identify the scent's owner should you meet
Just a random idea that's meant to be more for fun, than impact, and to make players under the influence of the buff feel a higher level of unease leaving home with murderous intent. Murder is serious business.
