Pro Tip: Press 'R' while hovering over any item to see its recipe instantly.

2. Magic Storage

Why it's essential: Revolutionizes storage with unlimited capacity and crafting integration. Never worry about inventory management again!

Pro Tip: Build your storage system early - it gets harder to organize later!

Why it's essential: Tracks your progression through all bosses, including modded ones. Shows you what to fight next and how to summon bosses.

Pro Tip: Use the integrated boss summoning feature to quickly respawn bosses for farming.

4. Wing Slot

Managing and Organizing Mods

The Golden Rules of Mod Management

Common Beginner Mistakes to Avoid

Installing Too Many Mods at Once

The Solution: Start with 3-5 essential mods, play for a while, then gradually add more.

Ignoring Mod Compatibility

The Problem: Some mods don't play well together or require specific versions.

The Solution: Always read mod descriptions and check compatibility notes before installing.

Not Backing Up Saves

The Problem: Mod conflicts or updates can sometimes corrupt saves.

The Solution: Copy your saves to a backup folder before making major mod changes.
