Question: If a tincture has a specified range (i.e. 1350 units), does this mean that damage from an enemy outside of the 1350 range (such as a caster or archer) would not be affected by the reactive but that those that are closer will?
Answer: Yes. If, for example, you are wearing a piece of armor with a reactive tincture having a range 1350 units, an archer who shoots you from 2000 units shouldn't be affected.. However, there's been a long standing bug that it still will "hit" the archer. But in general yes, the enemy still has to be within the tincture's specified range for it to work.

Was fixed with Patch 1.88B:
Reactive procs on armor will now only hit the archer if the archer is within range.

Don´t know if it is working as intended here on Phoenix.
But I agree, I found that behavior really stupid that an archer can possibly be hit by a reactive armor proc while shooting from distance...
