IV Fruits and Training Crystals are the endgame items that push a Pal past its normal ceiling. IV Fruits raise a Pal’s hidden Individual Values, with Life Fruit boosting HP, Power Fruit boosting Attack, and Stout Fruit boosting Defense. Training Crystals feed levels directly into a Pal. Both are hard to find in the open world, so the fastest supply comes from a small set of repeatable methods.
Quick answer: Defeat the Moon Lord raid boss on repeat. Each clear guarantees 4 Training Crystals and gives a 33.3% chance to drop 3 of each stat fruit, making it the highest yield per run in the game.
Moon Lord raid boss: the highest-yield source
The Moon Lord is the single best target for stat fruits and Training Crystals. It has no elemental weakness and over one million HP, so the fight is long and unforgiving. Come in at level 65 or higher with strong Pals, and bring friends if you are on a dedicated or multiplayer server. Every clear pays out the same reward table below.
| Item | Drops | Drop rate |
|---|---|---|
| Training Crystals | x4 | 100% |
| Life Fruit | x3 | 33.3% |
| Power Fruit | x3 | 33.3% |
| Stout Fruit | x3 | 33.3% |
To summon the boss, place a Celestial Sigil on a Summoning Altar. During the fight, aim for the eyes on its hands and forehead, which are the only reliable weak points. Once it falls, the rewards drop on the spot and land in your inventory, so you know the run counted the moment the loot appears.
Build a repeatable Moon Lord farm at your base
The real speed comes from summoning the Moon Lord at your own base instead of traveling to the raid area every time. Set up a steady Celestial Sigil supply and a fast rebuild loop, and an hour of runs can net hundreds of stat fruits.
Raid Feybreak bases for Legendary Treasure Maps
Three bases in Feybreak are guaranteed to hold a Legendary Treasure Map when raided, and the treasure chests respawn every 30 minutes. These maps can point to IV Fruit and Training Crystal locations while also dropping other endgame loot. The guarding enemies are tough, so make sure both your Pals and gear can handle endgame threats before you attempt them.
| Item | Drops | Drop rate |
|---|---|---|
| Training Crystals | x1 | 100% |
| Life Fruit | x1 | 33.3% |
| Power Fruit | x1 | 33.3% |
| Stout Fruit | x1 | 33.3% |
To restart a base, you also need to set the trapped Pal free. Freeing it begins the 30-minute respawn timer for that base’s Legendary Treasure Map. Rotate between the three locations below and you always have a chest ready to open.
| Base | Location | Coordinates |
|---|---|---|
| 1 | Ship Base, Feybreak | -1495, -1744 |
| 2 | East Ocean, Feybreak | -986, -1670 |
| 3 | Northwest Ocean, Feybreak | -1461, -883 |
Buy IV Fruits and Training Crystals with currencies
Three merchants let you target a specific fruit instead of gambling on drops. Each takes a different currency, and only two of them sell Training Crystals. This is the slower path, but it is reliable when you need one exact stat fruit.
| Merchant | Currency | What it sells |
|---|---|---|
| PIDF Bounty Officer | Successful Bounty Tokens | Life, Power, and Stout Fruit at 25 tokens each, plus Training Crystals |
| Medal Merchant | Dog Coins | Each stat fruit at 200 Dog Coins; no Training Crystals |
| Arena Merchant | Battle Tickets | Each stat fruit at 100 tickets; Training Crystals at 50 tickets |
The Bounty Officer sits in the Small Settlement and takes Bounty Tokens earned from defeating human bounties. The Medal Merchant is near the Isle of Silence Church Ruins fast travel point and only accepts Dog Coins, which you gather by beating Mimogs, looting Scraps and Junkyards, and opening chests. The Arena Merchant is by the Arena Entrance and trades in Battle Tickets from Arena challenges, but tickets come in slower than the other currencies.
How to use the fruits and confirm the boost
To spend a stat fruit, open your inventory, consume the item, then pick the Pal and the quantity you want to use. Each fruit raises that Pal’s matching IV by 10 points, so a Life Fruit adds 10 to its HP IV, a Power Fruit adds to Attack, and a Stout Fruit adds to Defense. Equip the Ability Glasses accessory to read a Pal’s IVs and confirm the increase after feeding.
Stack the Moon Lord loop for volume, keep the three Feybreak bases on a 30-minute rotation for renewable drops, and use the merchants when you need a specific fruit. Between those, you can lock a Pal’s IVs before breeding and level fresh projects up to your cap without waiting on random luck.
