The spell in general dose NOT work like its counterparts Sneak and Invisible. It's actual use is to rid the player of agro from monsters that track a player by smell. Because most do not know of its actual effects it goes unused 99% of the time in wich it can be considerd a useless spell. Furthermore, other than Crawlers, dose anyone know witch mobs actually track by smell?
Here is my thoughs on making this spell more usefull. Alow Deodorize mask the smell of Blood agrows.
There have been times when a party wipes due to the overpowered undead that pop at night in an area. even after a raise is performed and a cure been given to a player, after the weakness period is over, a player ones again falls into red and is subject to blood agro. As of now there is noreal way of preventing this type of agro from accuring.
On another note, this would also give thoughs of low maned partys or soloests a higher chance of survivle in surten areas seeing as even a resting high level player with sneak can still be blood agrowed while resting. And I know how inbarising it can be when a lower level mob just happens to get that lucky shot in.
