You are level 10, as you try to run to another location on the map, you come across a bunch of auto-aggro lvl 15 mobs that can kill you in 2-3 hits. You activate "sprint" (however you do it) to save your weakling behind, and burn up all your TP.

Your 1000 TP just saved you from a brutal death. Nothing lost, nothing gained. There is nothing wrong with running away from death, and come back to fight another day.
