Similar to locate object, but locate life would return locations for mobs instead of items. The spell should display the area name of matching mobs, and possibly the specific room as well. Would be limited by locate object spell in the same manner that certain mobs can't be located and that mobs above caster level would not be found at all.
If this is done, can we get some sort of argument/flag for "locate object" spell that allows us to only locate items on players?
Every time I try to locate a key my eyes bleed with all that mobs key spam.
isn't that what a perfect check with the lore skill does, or something quite similar? I thought it told the player the location/area where they would find the item, just not the specific mob? 
I thought that's why Bards get both lore and locate object.
Maybe, but who practices lore?
