Turn Your Digifarm Into a Powerhouse — Crash Course Skills & Best Training Sets in Digimon Story: Time Stranger

The Digifarm in Digimon Story: Time Stranger is where your Digimon train, change personality, and gain bond — and it matters for evolution. Here’s a clear, friendly guide to how it works and the concrete upgrades you can use to get better results.

The farm in Digimon Story: Time Stranger, explained

The Digifarm lets you place up to 30 Digimon to earn EXP, train stats, or shift personalities. All Digimon on the farm earn the same EXP as the Digimon in your box, so it’s useful for bulk growth. However, you can only access the farm by entering the In-Between Theater and talking to Mirei Mikagura — it’s not an always-on menu you can open anywhere.

When you enter the farm, you’ll see a list of materials the Digimon have gathered. From there, choose “Interact with Digimon in Farm” to set training, feed them to raise bond, or remove them. To add a Digimon, select “Move Digimon.” You can place islands and decor on the farm, but those decorations do not change training effectiveness.

Training basics

Training uses Training Sets that target specific stats or personality shifts. There are three tiers: A, B, and C. Their durations are 30, 60, and 90 minutes respectively, and the timers use real-world time that only runs while you are playing (on PS5 the timer stops in rest mode).

There are a few concrete upgrades that make the Digifarm more productive. First, Agent Skills called “Crash Course” cut training time by 50% for specific personalities. Second, crafting higher-tier Training Sets (B and C) boosts stat or personality gains. Finally, certain NPCs let you craft or buy the materials needed for those sets.

Crash Course Agent Skills

The four Crash Course skills are:

Crash Course in Valor
Crash Course in Philanthropy
Crash Course in Amicability
Crash Course in Wisdom

Each reduces training time by 50% for Digimon with the corresponding personality. Therefore, equipping all four covers the main personality groups and speeds training across the board.

Crafting Training Sets (A, B, C)

Training Set A is the baseline. Training Set B greatly increases stats and personality, while Training Set C vastly increases stats without changing personality. Use B when you want both stat and personality growth; use C when you want stat boosts but no personality shift.

To craft training sets, speak with Zudomon in Central Town (and later in Rebellion Village). B and C versions became available after completing the side missions “The Blacksmith’s Request” and “The Craftsman’s Partner.” Most materials are sold at the shop inside the In-Between Theater. After the main quest “On My Life,” Wendigomon in Central Town can craft some required materials.
