Description

⚡ StealthCore

Fast, Smooth, Unstoppable — PvP Ready

A lightweight, client-side Fabric modpack built for competitive Minecraft. Every mod earns its place. Nothing is wasted.

🎯 Overview

StealthCore is a combat-focused optimization modpack for Minecraft Java Edition 1.21.1 & 1.21.11 running on Fabric. It's fully client-side — drop into any server and every feature works immediately, no server-side install needed.

The goal is simple: more FPS, sharper controls, cleaner UI, better information — everything a serious player needs and nothing they don't.

⚔️ Combat Features

Feature	Description
Fast Block Placement	Snappier, more responsive block placement for clutch builds and fights
Quick Elytra Swapper	Instantly swap elytra ↔ chestplate with a custom keybind
Totem Counter	Always-visible count of totems in your inventory
Saturation Gain Icons	Real-time HUD icons showing hunger and saturation state
Optimized Settings for PvP	Pre-tuned game settings ready from first launch

🖥️ Interface & HUD

Custom HUD — Press O to open the live HUD editor. Move, resize, and toggle any element
PreOptimized HUD — A clean default layout ships ready to go, no setup required
Darked Themed UI — Full dark aesthetic across all menus and inventory screens
Better F3 — Cleaner, reorganized debug screen so you find info instantly
Task Manager via F12 — In-game CPU/RAM overlay without alt-tabbing (1.21.11 only)

📚 Information & QoL

Just Enough Items (Integrated) — In-inventory recipe lookup and item info
Optimized Enchanted Books — Clearer, more readable enchantment tooltips for smarter gearing decisions

🚀 Performance

Lightweight by design — No bloat, no redundant mods, no unnecessary rendering
Client-side only — Works on any standard Java server out of the box
Chunky (included) — Pre-generate chunks before playing for maximum smoothness

⚠️ Chunky will not boost FPS unless configured and run. See the Chunky mod page for setup.

🎨 Visuals

Optimized PvP Texturepack — Sharp, clean visuals with minimal performance cost, enabled by default
StealthPaints (Disabled by default) — Optional custom paintings pack. Enable in resource pack settings when ready
