I need Bat Hook

I’m playing an extremely pre-hard mode and have only skeletron and WoF to defeat. I’m at the point where I collect basically every accessory that’s best like Terra spark and Bundle of Balloons that I only need one item: Bat Hook. In order to achieve my fully maxed loadout, I need the best pre hard mode hook. I changed my time to October and farmed so long for it using water candles, battle potions, and spawning a blood moon for 10+ times and all in all it took so far 3 hours of non stop grinding to get in total 50 of those bags. Those bags however only have a 0.67% chance to get bat hook and I haven’t gotten it in those bags… Please tell me if I can either be able to save before opening new ones that I can get a new one. If I can’t I beg anyone to provide me an extra they have.
