If you're tired of the Blood Moon respawning everything you kill, then you are going to love this. On a night where you can see that the Blood Moon is rising, take yourself to any shrine throughout the world and taking care to keep a close watch on your in game time, go in just before midnight. You can either wait until you think it's safe to leave again or just run through the shrine's puzzle and then leave. If enough time has passed the Blood Moon event will not have triggered and you can go about your business without worrying about pesky respawns until then next scheduled Blood Moon event.
