Q85: A situation: A character is using the pincer staff from Underdark to grapple an opponent. The character is under the influence of an enlarge person spell, so has his foe grappled at 20' away. The spell wears off, reducing the reach to 10'. What happens to the grapple? On one hand, his foe is 20' away, and his reach is only 10', implying that the grapple effectively ends. On the other hand, it's a grapple - it also seems reasonable that someone gets dragged.
Thoughts?
