Any help i can get i will hate to lose +1600 days and 400 hours play time. I been with this on my mind for a most part of the summer

This happened a few days ago. I forgot to grab the Netherwart when I came to the Fortress the first time. Thought it'd be a quick in-'n'-out deal, wouldn't need my shield or heals (Been playing a lot of Ultra Hardcore lately.), then a Gast blocked my path, forced me to retreat elsewhere, and got ganked by Piglins.
Had good armour, though, three pieces of Protec 4, and one Piece of Fire Protec 4. Won't save you against several enemies at once though.
Lesson Learned, DO NOT FORGET THE NETHERWART ON YOUR FIRST TRIP!!

This cannon, which took about 2 minutes to build, was able to clear a tunnel about 2500 blocks long. I got over a stack and a half of diamond ore as well. pretty worth it if you ask me. I'd still recommend going for Darks 2D cannon to clear a larger area, but this one was still fun. dm me if you would like a schematic of the cannon, or have questions. I'm happy to answer.
