Invisibility: Blood and Sand

[Ravingdork]

If I cast invisibility (4th) on myself and stab someone, can their blood be seen on my invisible weapon? If I throw sand, powder, or paint on an invisible target can the substance be seen, or does it turn invisible too?

There seems to be some disagreement on the matter in our group.

I think details like that would be relevant if and when a creature becomes observed as the reason. Typically you become observed when you make an attack but are still technically hidden if you remain invisible. If you mean to make something concealed instead of hidden, it would have to be pretty substantial if the target is invisible. Such as faery fire or a different sense. There isn't any raw on if an invisible creature falls in the mud or something, so it'll probably just come down to interpretation. I'd say things that are worn or carried when the spell is cast remain invisible, and anything else sticks out and a creature could spend 1 or 2 actions to rid itself of the thing to stay invisible. In most cases it would still be hidden unless they're completely covered in something foreign.

Falls under the sort of circumstantial adjudication described on CRB page 467:

Quote:

Other effects might make an invisible creature hidden or even observed but concealed. For instance, if you were tracking an invisible creature’s footprints through the snow, the footprints would make it hidden. Similarly, throwing a net over an invisible creature would make it observed but concealed for as long as the net is on the creature.

I dont see any reason to think that paint couldn't do what a net could.

Hadn't realized the CRB had this covered. Pretty straightforward then.

That sounds like a too bad to be true ruling. What exactly is the point of 4th level invisibility then?

I think Hammerjack has the right of it.

There is also Powder that could be looked at as an example.
