The defender can use a Spot check DC 30 to detect the invisible creature (Inanimate or Undead creatures are DC 40). A plus +20 penalty to the DC is incured if you're trying to pin point the location of the invisible creature (as per Sutek reference.)
Good stuff overall. One thing I wonder about is from the quote above. What does it mean to "detect" the invisible creature? It doesn't seem to mean the ability to attack it, as that seems to require pinpointing the location and still incurring the 50% miss chance...
