A word about Skill Challenges- past, present and future. I know you like to use the skills that you are good at but... well, consider this- I want the story to go on and you want the story to go on.
The story will go on. Bad results result in '?' and not the end of the story, not even anything too bad sometimes (although not all the time).
So roleplay is good, always makes me want to give bonuses to any roll you make.
And there are plenty of other ways of using the various skills, for example-
Acrobatics- I should imagine that a degree of manual dexterity is needed to ensure the child doesn't suffocate and die (strangled by the umbilical cord).
Athletics- as acrobatics really, and for Velani to PUSH!
Bluff- to chat and calm Velani down...
Diplomacy- see Bluff.
Endurance- certainly of use for Velani, as demonstrated previously.
Heal- obvious really.
History- anyone remember anything about childbirth, undoubtedly some of you have been around for the birth of siblings, or else witnessed other such events in the past- maybe.
Intimidate- if things are going bad then a little bit of tough talk wouldn't hurt matters, nice speech to go with it and good as gold... Velani my be panicking, hysterical.
Nature- as demonstrated by Kyalia.
Perception- how are things going down there, take a look- see what needs to be done next etc.
Religion- can't imagine that a prayer or two would go amiss at this point.
Go for it people...
And leave the mystery till the present dilemma is resolved.
Cheers PDR
