When you say "map", do you mean that you are exploring and making mental notes, or that you are actually attempting to render this to some form of cartographic record?
Your clairvoyance runs for stretches between one minute and maybe half an hour or so. You can keep restoring it, but it does get tiring. The viewpoint moves at between one and three miles per hour, and interestingly there is a correlation between how fast you can move and how long the skill lasts, suggesting that the better you make the initial connection, the better both of those factors are.
Another interesting limitation. Let me ask a couple of questions:
1) Does this mean that if I was at sea where I can only look at the ocean I could not start from there because there is no fixed objects there unless I dive to the bottom of the sea (or does celestial constellation during a certain time counts as fixed objects)?
Actually, you always count as a fixed object, because within your own frame of reference you always know where you are.
It would be different attempting to find the ship at sea; it is not fixed within a frame of reference that includes you. However, if you can see the ship with your eyes, it is fixed within your frame of reference relative to you, and you can move to it clairvoyantly.
2) Does this work on location that will be moving such as the interior of a ship?
If you are on the ship, it is fixed relative to you; if you have already established a clairvoyant connection with the ship, it is fixed relative to the clairvoyant connection. If you can see the ship, either actually or clairvoyantly, you can immediately move to a point on the interior of the ship (by using the skill (rolling) afresh) if you can define that point based on what you are able to see. You can't say you're going to jump to the captain's quarters, but you can say that you're going to jump to ten feet inside the aft castle below the top deck.
3) If the above works, which location will the vision start when the ship starts to move?
You can define the frame of reference. If you make the frame of reference the ship, then the clairvoyance moves or does not move relative to the ship; if you make it the sea, then the ship moves relative to the clairvoyance and you have to move to keep even.
4) If the ship for the above example is replaced by bird because sprite could possibly ride a bird, would the vision be traveling along with the bird?
I am not certain I understand this. If you are watching the bird, the bird becomes your frame of reference; if you turn away from the bird but keep the bird as your frame of reference, your vision sees the world moving and the bird as stationary. That can make you dizzy, of course, but not more so than the motion sickness you might get riding the bird.
5) Can I look at the moon then start clairvoyant from there then look back to earth then target any location on earth that is visible from the moon?
Technically yes, but the distance from the earth to the moon is great enough and the relative motion fast enough that any such attempt would be very inaccurate. The level of accuracy would be dependent in part on the nature of the target point. If you're looking at the tip of Cape May, New Jersey (that tail that sticks down between the Atlantic Ocean and the Delaware Bay) you probably can hit within twenty miles or so of the desired point on the shoreline. If you're looking at the middle of the Great Plain, it could be several hundred miles from where you hoped to hit.
Sure enough, I don't know how I overlooked it, but you do have "1@1 Locate telepathically known person P3@1" It appears that that skill identifies direction but not distance, though, and so it does not really give you the location in the sense necessary for clairvoyance.
You only get new use credit when you succeed in a new use. I understand that failure is part of the lesson, but we don't give credit until the accumulated failures lead to a success. Note that in probabilistic terms, the fact that you can roll again increases your chance of success. (Your chance of not rolling 1 on a d10 in one roll is 90%, but your chance of not rolling 1 on a d10 on two rolls is only 81%.) The down side is that you might botch, which does not increase your skill level but might teach you something anyway.
You need more agility and hand/eye for the intuition practice; haste does not give you this, it just makes you quicker. To put it in perspective, if every hundred steps you were stumbling and catching yourself, you are still stumbling and catching yourself every hundred steps, you're just making those hundred steps maybe as much as 40% faster.
And with that we will advance to May, when you are 14 months old, if I'm reading my notes aright. I have no developmental milestones for this month.
