This patch serves as a refinement phase, optimizing the systems introduced in earlier versions to ensure smoother progression and strategic depth.

The Alchemist: Adjustments have been made to balance damage output more effectively compared to other classes.

Information regarding the latest builds and the project roadmap can be found on the official development pages on Itch.io. Supporting the developer through their official channels often provides access to more frequent updates and experimental features.

3. UI & Performance Fixes

Anyone who played Beta 132 knows the inventory lag was frustrating. The UPD addresses this:

  • Inventory loading times reduced by 40%.
  • New "Auto-Sort" button for loot.
  • Tooltips now correctly display the new "Ero Dungeons Beta 133" scaling formulas.

How to Download Ero Dungeons Beta 133 (Official Sources)

Warning: Be cautious of fake uploads. MadoDev only distributes via two channels.

  1. MadoDev’s Patreon ($5+ tier): The earliest access. Beta 133 went live on October 26th.
  2. Itch.io (Public Beta): The public version usually lags 1 week behind. As of today, Beta 133 is available for free with a "Name Your Price" option.

Installation steps for the UPD:

  • Do not install over Beta 132. MadoDev changed the save schema.
  • Back up your save_data.json from the old folder.
  • Delete the entire Ero_Dungeons_132 directory.
  • Extract Ero_Dungeons_b133.zip to a new folder.
  • Run Ero_Dungeons.exe as administrator (to allow for config file writes).

Technical Notes for Players

If you are looking to install or play the Beta 1.3.3 update, consider the following:

  • Save Compatibility: Usually, minor patches (like moving from 1.3.2 to 1.3.3) allow players to carry over their save files. However, it is always recommended to back up your save folder (often found in AppData or the game directory) before patching, as procedural generation seeds may change.
  • Performance: If you experienced frame drops during heavy particle effects (common in dungeon crawler abilities), this patch likely optimizes those rendering calls.

If you are jumping into Ero Dungeons Beta 133 by MadoDev UPD today, forget your old strategies. The tier list has shifted.

Quality of Life

  • Inventory Search Bar

    • Filter items by keyword, type, or status effect.

  • New mechanic: Fervor – At 80%+ Lust, physical damage increases by 25%, but defense drops to zero.
  • Updated scenes: Beta 133 adds 4 new interactive loss scenes for the "Cultist" and "Ranger" classes.

How to Download the Correct Version (Avoiding Fakes)

  1. Official Sources:
    • MadoDev’s Patreon (Tier $5+ gets early betas).
    • Itch.io (Public demo up to Beta 130; full Beta 133 is Patreon-only until May 20).
  2. File Verification:
    • Correct file name: EroDungeons_Beta133_UPD.zip
    • MD5 Checksum (provided by MadoDev on Discord): f2a8d9c1e4b5...
    • File size: Exactly 1.24 GB (the broken build was 1.21 GB).
  3. Avoid:
    • Any site listing “Beta 133” without “UPD” in the filename.
    • Torrents uploaded before May 6 (they are the corrupted build).

What Does “UPD” Mean in “beta 133 by madodev upd”?

The search term includes “upd” – this is shorthand for “Update” or “Hotfix” . Here’s why it’s needed: Inventory loading times reduced by 40%

  • Initial Beta 133 (May 3): Broken. Users reported that the new Echo Stone system caused save file corruption when loading a game saved inside a dungeon.
  • Beta 133 UPD (May 5): MadoDev released a 14MB hotfix. The “UPD” version does the following:
    • Rolls back the save serialization to Beta 132’s format.
    • Re-adds Echo Stones as a separate JSON file instead of embedding them in the main save.
    • Fixes a typo in the Orc Warlord scene that caused a softlock (the game would freeze on a missing image file: orc_ending_03.png).

Important: If you downloaded Ero Dungeons on May 3 or 4, you are on the broken build. You must search for “ero dungeons beta 133 by madodev upd” to get the stable version.
