this is a really cool concept pirate101 has this a few times, not just from getting the boss to low health but also in other ways with different "battle conditions." theyre nice breaks from the repetition of "defeat to win" combat, and they can also integrate into the storyline in fun ways. bosses fleeing/surrendering in wiz could do the same thing... winning the fight in other ways besides defeat would be super interesting, theres a lot of potential for more creative combat, cheats, etc with bosses... thank you for sharing this idea
Yes this would save time and in theory it would make sense however that cannot happen because it would ruin the point of the game. Also, technically the boss does flee once you defeat it.
