What is the best Hypixel Skyblock mod for 1.21.11?

SkyblockMod is the best Hypixel Skyblock mod for Minecraft 1.21.11. One single mod with all features of 35+ mods combined. Dungeons solvers, farming tools, mining helpers, performance. Drop one .jar file and play.

Is this mod safe to use on Hypixel?

Yes, 100% safe. The mod is client-side and follows all Hypixel rules. No automation, no unfair advantages, no risk of bans.

Why one mod instead of a modpack?

Modpacks with 25+ mods cause compatibility issues and crashes. Our single mod gives you the same features with zero hassle. No more managing updates for dozens of mods.

I'm coming from 1.8.9, will this work for me?

Absolutely! This mod includes all features from NEU, SBA, Skyblocker, SkyHanni, and more -- rebuilt for modern Minecraft with better performance.

Game crashes on launch after installing mods

Make sure you're using Minecraft 1.21.11 with Fabric loader (not Forge). Verify Java 21 is installed. Try allocating more RAM (4-6GB minimum).

Mods not showing up in game

Check that the mods folder is in the correct location inside your instance directory. The .jar files should be directly inside the mods folder, not nested in a subfolder.

Low FPS even with performance mods

Allocate more RAM (6-8GB). Make sure you're not running OptiFine alongside Sodium. Close other programs like Chrome or Discord overlay.

Troubleshooting

Common issues and how to fix them

Make sure you're on Minecraft 1.21.11 with Fabric loader (not Forge or NeoForge).
Verify Java 21 is installed. PrismLauncher will warn you if it's missing -- Modrinth and Feather include their own Java.
Allocate at least 4GB RAM (4096 MB). With 25 mods, less than 4GB will cause out-of-memory crashes.
If you added extra mods beyond the pack, remove them. They may conflict with included mods.
Delete the .fabric folder inside your instance and relaunch -- this regenerates mod configs.

If you imported the .mrpack correctly, all mods should be auto-installed. Try removing and re-importing the modpack.
Check that Fabric loader is installed for the instance -- the .mrpack should handle this automatically.
Make sure you're launching the correct instance (the one created from the .mrpack import).
Restart your launcher completely and try again.

Allocate 6-8GB RAM if your system has 16GB+ (but never more than half your total).
Make sure OptiFine is NOT installed. OptiFine conflicts with Sodium and will tank your FPS.
Close browser tabs, Discord overlay, and other heavy apps while playing.
In video settings (Sodium options), try lowering render distance to 12-16 chunks.
If you're on a laptop, make sure Minecraft is using your dedicated GPU (not integrated graphics). Check your NVIDIA/AMD control panel.

Some features need to be enabled manually. Open settings with /sh (SkyHanni) or /skyblocker (Skyblocker).
Make sure you're on Hypixel Skyblock -- these mods only activate on Skyblock islands, not in the lobby.
If features are grayed out, check if they require a specific Skyblock profile type or island.
Try updating the mod configs: delete the config/skyhanni or config/skyblocker folder and relaunch.

This modpack is for Minecraft 1.21.11 ONLY. Check that your instance is set to exactly 1.21.11, not 1.21, 1.21.1, or 1.21.4.
Make sure Fabric Loader is up to date (latest version). Update it through your launcher.
Don't mix mods from different Minecraft versions. Remove any manually added mods and try again.

This is usually a Hypixel issue, not a mod issue. Check Hypixel's status on their Discord or Twitter.
Make sure your Minecraft account is a Java Edition account (not Bedrock).
Try connecting to mc.hypixel.net with port 25565 (the default).
If you're getting kicked immediately, check if any of your mods are sending disallowed packets. The mods in this pack are all Hypixel-safe, but manually added mods might not be.

Make sure you're using 'Install from file' (the + button), not dragging the file into the app.
Check that the .mrpack file isn't corrupted -- try re-downloading it.
Update Modrinth App to the latest version.
Try restarting the Modrinth App completely before importing.

Still stuck? Most issues are caused by wrong Minecraft version, missing Java 21, or not enough RAM. Double-check those three things first.
