Suppose there was a gate keeper blocking your way. You enter battle, take off 25% of its HP, and then you run away (ie: so-called tactical retreat) Then you come back 5 seconds later and re-challenge it. It will start the battle off with 75%. So basically if you enter a battle, and then later come back to the same battle, the state of the enemy is the same as when you left. What would be a good name for this mechanic?
