I host a Shell Challenge each month from my discord and Twitch channels. I need to be better about promoting them, however, so that’s what this section is for. Every first or second Wednesday of the month is tour night, and I tour everyone’s submissions on this night. If you cannot attend (or don’t get done in time for the deadline), I am more than happy to tour any completed shell challenge for free at any time you are able to stop by a sims stream on my Twitch channel.
That being said, this section is also all about having a record of all the shell challenges I’ve done in the past. I have, from very early on, always tried to make each of my shell challenges be a bit of a brain-teaser. Something that will make you think. Either with a theme, or a puzzle/problem, or coming up with a story in your head to match your build. I am perpetually coming up with new ideas, so don’t expect these challenges to stop anytime soon – I have at least through 2024 and most of 2025 already either planned, or the ideas sketched out. In some cases, they’re already even built and ready to go except for their promo graphics.

Understanding Anti-KB Mods in Minecraft 1.8.9 (Anti-Knockback) mods for Minecraft 1.8.9 are tools—often categorized as cheats or "hacks"—designed to reduce or completely eliminate the distance a player is pushed back when taking damage. In competitive 1.8.9 PvP, movement and positioning are critical; being knocked back can break a "combo" or send you off a ledge in game modes like SkyWars or Bedwars.
Since using Anti-KB mods on most servers will lead to a , skilled players use "legit" techniques to reduce knockback:
Some mods allow you to take normal vertical knockback (popping up) while taking zero horizontal knockback, making it harder for moderators to tell you are cheating. Top Legal Alternatives to Anti-KB Mods
Technically, Anti-KB mods intercept the game's internal physics. When a player is hit, the Minecraft client typically calculates a change in (speed and direction).
Advanced versions allow players to set "multipliers" (e.g., 0.5 for 50% knockback or 0.0 for zero knockback) to make the effect look more natural and avoid detection by anti-cheat systems.
While some players seek these mods to gain an advantage, others look for legitimate ways to achieve similar results through gameplay techniques.
These mods use tools to find and modify the velocity values in the game's memory.
