Is there any way to get monsters to give up chasing you? It seems like if you aggro something bigger than you can handle, you're on the run for the rest of the game.
1. Get to the castle, save and restore.
2. Get to the healer, heal up and hopefully you'll be able to beat the monster with restored health.
But yes, it's not something I considered. Thank you for pointing that out! I'll try to think of a way to deal with it.
