In the campaign I am running, the party just had its first encounter with a little white dragon. It worked them over with its breath weapon quite a bit doing a bit of damage here and there vs the resist energy protection that they had and used its fog cloud and blindsense to great effect. The little bugger used its ice walking ability to cling to the ceiling 15' up and harass the party a bit. One of the characters tried to claim that this was a little unfair to the melee fighters because each individual only takes up a 5' cube and couldnt actually reach the dragon without jumping. It got even worse when the dragon dropped another fog cloud in the room and by the rules and this persons interpretation the party couldnt ever see the dragon because it was more than 5' away. Are there rules that support this or are creatures on the roof the bane of 6'6" warriors with swords?
