The New Quest System Explained

Part 4 introduces a dedicated quest stand where you can pick up and complete Harvest Moon Quests. You get three active quests at a time, and once you finish them, three new ones take their place. If you're not in the mood for a specific quest, the reset happens every 4 hours, so you're never stuck grinding something you don't want to do for too long.

Each completed quest grants 1 point, and these points feed directly into the Harvest Moon Collection. That collection tracks your progress across seeds, pets, and cosmetics from the event, so the quests aren't just busywork; they're your main path to unlocking the good stuff before the event closes out.

If you're short on time or just don't feel like doing a particular quest, you can skip it, though that comes at a cost. Whether you grind them out manually or spend to skip, the goal stays the same: rack up enough Collection progress to hit that 80% mark and claim the reward tied to it.

All Grow a Garden Harvest Moon Part 4 Rewards

Part 4 comes packed with a long reward track, and it's one of the more generous lineups the event has offered so far. You'll be climbing through 20 tiers, each one unlocking as you complete quests and rack up points, and the further you go, the better the payout gets.

The grand prize sits at tier 20: the Eclipse Berry Seed, a Prismatic-tier reward and easily the best item on the entire track. Getting there means grinding through quests consistently, so if you're aiming for that final seed, treat every quest reset as a chance to close the gap.

What Was Added in Part 4?

Part 4 is confirmed as the final installment of the Harvest Moon event, and alongside the new quest system and Collection, it brings a few extra additions worth knowing about.

• A new plant added to the event's crop lineup
• A new pet joining the existing Moon Egg pool
• A new cosmetic item added to the Harvest Moon collectibles
• The exclusive Harvest Moon Shovel skin, unlocked once you hit 80% completion on the Harvest Moon Collection
• A batch of fixes and quality-of-life improvements addressing issues from earlier parts of the event

Since Epic hasn't detailed exact names or stats for the new plant, pet, and cosmetic yet, players will likely find out more as they roll out in-game. Given this is the last part of Harvest Moon, it's worth checking out everything Part 4 brings before the event closes for good.

Conclusion

Harvest Moon Part 4 closes out the event on a high note, giving players a real reason to keep farming Moon Coins until the very end. Between the new quest stand, the 20-tier reward track, and the extra content tucked into this update, there's plenty to chase before Harvest Moon disappears for good. If you've made it this far into the event, it's worth pushing for that 80% Collection mark and the Eclipse Berry Seed at tier 20, since both are the best rewards this event has offered so far.
