Note: Mod 15 refers to the fan-made expansion by The Pharaonic Guardian (based on the original "Mod 7" by RedHeadJedi). It adds over 700 cards, new duelists, and rebalanced drop tables. This guide focuses on the Standard Release of Mod 15.
These are your primary farming spots for the first half of the story.
| Opponent | Key Drops (S-Rank Required) | Use / Fusion Path | | :--- | :--- | :--- | | Ishizu Ishtar | Mystical Beast Serket, Kaiser Glider | Serket + Temple of Kings combo is legal in Mod 15 | | Yami Bakura | Dark Necrofear, The Earl of Demise | Required for summoning Necrofear (unique win condition) | | Seto Kaiba (1st) | Blue-Eyes White Dragon, Judge Man, Kaiser Dragon | The classic farm. Still takes time, but rates are 3x vanilla. | | Pegasus (1st) | Relinquished, Thousand-Eyes Idol, Toon World | Relinquished is a top-tier utility card due to its removal effect. |
Knowing the drop list is useless without a strategy. Here is the optimized path to conquer Mod 15.
In vanilla Forbidden Memories, each opponent has a drop pool of roughly 30–50 cards, but only 4–8 are realistically obtainable without max Tec. Powerful fusions like Twin-Headed Thunder Dragon or Meteor Black Dragon require winning duels with perfect performance — often forcing players to grind low-level duelists for key components like Thunder Dragon or Meteor Dragon.
Mod 15’s drop list redistributes rarity logically. For example: Yugioh Forbidden Memories Mod 15 Drop List
The result: a progression arc where each victory feels rewarding, not exhausting. Players can plausibly build a viable fusion deck by the game’s halfway point without savescumming or TAS-level play.
After beating Heishin 3rd (DarkNite), the game unlocks "Free Duel" mode with exclusive drop lists for gods and legendary cards.
| Opponent | Key Drops (S-Rank Required) | Rarity in Mod 15 | | :--- | :--- | :--- | | Shadi | Millennium Shield, The Winged Dragon of Ra (Sphere Mode) | Ultra Rare (1/256 S-rank) | | DarkNite (Heishin 3rd) | Meteor B. Dragon, Black Skull Dragon | Super Rare | | Seto Kaiba (3rd - Final) | Blue-Eyes Ultimate Dragon, Obelisk the Tormentor | Ultra Rare (1/512) | | Yugi Muto (Final Boss) | Slifer the Sky Dragon, Dark Magician of Chaos, Exodia pieces | Ultra Rare (1/1024 - Rarest in game) | | Pegasus (Final Form) | Thousand-Eyes Restrict, Manga Ryu-Ran | Rare |
Crucial Tip: The Winged Dragon of Ra in Mod 15 actually works. You must tribute 3 monsters, and its ATK/DEF becomes the sum of the tributes. It replaces the old "Meteor B. Dragon" meta.

A: No. Mod 15 includes "junk drops" intentionally to preserve the original game's feeling. Even at S-Rank, 40% of drops will be common cards. You must grind.
Do not farm Joey for Red-Eyes 100 times. Instead, rush to the Paradox Brothers. Use Twin-Headed Thunder Dragon (fuse two Thunder Dragons bought from the shop) to S-Rank them. Get Gate Guardian (2600 ATK). This card alone will let you S-Rank 90% of the story mode. Note: Mod 15 refers to the fan-made expansion
