Does the damage go up based on:

- Time spear traveled to target

or

- Nidalee's distance from target at time of impact

distance spear travels from area or launch, thats why advised ot throw cross walls and bush to catch people off guard and get the distance

Distance from Nid to bad guy WHEN IT HITS. Its a good habit to throw and move away from them to maximize the damage when possible or useful. (not when chasing of course)

You could do the troll move, Spear, cougar, leap Flash away for max damage.

if you miss, you just wasted flash for nothing.
