As for the comparative distances (200 ft tunnel, up to 800 ft away), the 45 degree was just a fairly simple one for demonstration purposes - you can just as easily use a 2:1 ratio on the distances without knowing that such a ratio gives you an angle of about 26.6 degrees.  A 4:1 sides ratio could also be used, granting about a 14.0 degree angle (which has a decent chance of working with a 200 foot shaft and an 800 foot range).  At the extreme (BBEG is at the middle level of the 200 foot shaft and the max 800 feet distant) you can use an 8:1 sides ratio - with about a 7.1 degree angle (not that it matters).    You really only need similar triangles, not standard ones (other than to obtain a 90 degree angle to base the others off of).As for the issue about him moving, well, Locate Creature tells you if the subject is on the move.As for assuming the precision on Locate Creature, well, I am - sort of.  I picture it like being one of those hand-held seaman's tools that lets you hear a beacon if it's pointed in the right direction - if you are off just a hair, you can still hear the beacon, but it's a little fuzzy.  If you are pointed in the exact right direction, you hear it clearly (or most clearly; there can still be some static).  It obviously doesn't specify to such a degree what the accuracy on the spell is, so it's a DM call, either way.As for specific references for the location the spell gives (e.g., from head?  From feet?  To Head?  To Feet?) it seems like a wizard casting his spell ought to know such specifics of the mechanics on his spell, and thus be able to account for them, no?</blockquote>
