Infected Wounds Witch Hex question.

[ObligatoryHuman]

Ok, forgive me for asking a potentially stupid question, but after looking at the infected wounds hex I need to ask a couple things.

1. Is there a range? or is it just those I can see?
2. does it stack with itself IE, can I keep using it on one target and if they continually fail their save keep putting con damage on them?
3. Do they actually have to be wounded? Or can I use this on something with full HP?

Thanks in advance.

1. I never noticed that it doesn't list a range. I think you'd be safe going with 30 ft. Because it's a major hex, you might be able to justify 60, but I would say no one would argue with 30.

2. It's a disease effect, and I'm pretty sure you cannot make a disease worse (aka take double damage from filth fever or something). I don't have documentation to back that up, but I'd say you cannot stack it.

3. Again, no documentation, but a lot of witch hexes like this one use phrases like "the target's wounds become infected" as flavor text. I would say the target does not need to be wounded.
