Druid/Ranger spell: Sense Interlopers

[meow-mix]

Just an idea for a spell, probably enchantment or divination + or - level 3.  Would, when cast, update a druid or ranger for hour/level when any PC or perhaps when any PC in medium or heavy armor or capable of wizardry enters or leaves the area in which the spell is cast.
 
The idea behind it would be to help a druid or ranger be aware of when he might need to observe the goings on in or defend a specific claimed wilderness only area.
 
I.E. a garden area, or the place you stashed a herd of deer, or the route to a necromancy quest, or an opportunity to confront interlopers if you are the more militant sort of druid.
 
Divination if it was a sixth sense sort of thing, Enchantment if it was a "what the local plants/animals find abnormal/unnatural" sort of thing.

Besides using quests as pvp bait it seems like a nice enough idea, though perhaps they can just be given Alarm on a low level spell slot instead? It seems like it would function in the same way.

Well the idea was for a druid or ranger to be able to "Take ownership" of a wilderness area, without having to sit there all day long.  Alarm would let him take ownership of one bush.  :(

I really don't think it's possible to differentiate between what armor a person is wearing, and being able to ward a whole area sounds powerful.

Why based on armor? I feel like making a heavy armor ranger just 'cos I can.

I enjoy the concept behind it, but not the way it is presented.

Get your own arcanists to use Alarm, or patrol places.

Place it near the transition and we're good.

I like this idea.

This exists, is called Alarm, and can be cast by rangers and probably druids as well.

If you think the area for Alarm is too small, cast it twice on different spots.
