So, here is the situation. Large character (7'6" in height) in a cellar with a trap door on the roof. Trap door opens, large character has an action readied to grapple the guy who opens it. How to resolve the grapple?
RAW says to move the grappled character to an adjacent square. Is a square still adjacent if it is on another level of the building? I can totally picture this large character (a Giff) to be holding the legs of this guy who just opened the door. That is how I ran it. If he wanted to get him down through the door, I was asking for a move grapple action.
How should I have handled this by RAW? How could I have handled this?
In retrospect, I think I should have given the guy being grabbed (a cultist of sorts) the +5 bonus for being moved to a dangerous square (falling for 1d6 damage) and just move him adjacent to the Giff on the same level.
What say you!
Edit: The Cellar was about 6'6" high.
Your space as a large creature is a 10' x 10' x 10' cube So you'll have to determine where the character on the second level is in relation to the large creature. Just imagine the squares at the head level of the large creature.

The problem with elevation is there are, as far as I can tell, no real rules on this. Are squares 5x5x5? That doesn't really make sense, as it would make most creatures take up 5x5x10 squares. Essentially, the problem is 'how tall are squares' and 'can squares on different levels be adjacent'? Scaling the height of squares according to the height of any specific creature seems like an absurd solution (consider, for instance, colossal creatures fighting flyers).
