|Tastes longer than that, I'm afraid.|
The ability to sense things remotely is based on the advantage Clairsentience. The spell Far Tasting in vanilla magic can allow us to taste as far as we can see. Humans can actually see pretty far. So, I decided to alter it to mean as far as we can see on the Earth's surface, which according to a random google search, seems to be a little over 3 miles. Clairsentience has a normal range of 10 yards, and needs enough extended range to reach 3.1 miles or 5456 yard, or 1000x minimum for a 10,000 yard range and a 120% enhancement. We need to limit it to sight based as well, so we can't taste through walls, and we need to lower FP costs to 1.
Far Tasting (+50%): Clairsentience (Increased Range, 10,000 yards, +120%; Reduced Fatigue Cost, +20%; Mana Sensitive, -10%; Vision Based, -20%, Clairsomia, -60%) 
Precis - A weird support spell when you need to taste distant things.
