St. Patrick's Day Event Overview {#st-patricks-day-event}

The St. Patrick's Day event launched on March 14, 2026 and runs for one week. A leprechaun NPC has appeared in the event space, surrounded by pots of gold. Every hour on the hour, he activates the Rainbow Event, which is the key mechanic for this entire event.

Key features:

Hourly Rainbow Event triggered by the leprechaun

Luck mutation applied to growing plants during the event

Three donation pots around the map with unique rewards

Ultra-rare Four-Leaf Clover seed obtainable through donations

Limited-time cosmetics and gear

The event area is located near the main spawn — look for the rainbow arch and pots of gold to find the leprechaun.

---

How the Rainbow Event Works {#rainbow-event}

Every hour, the leprechaun activates a server-wide Rainbow Event. During this event:

All growing plants in the server are affected with the Luck mutation

The Rainbow Event lasts approximately 5 minutes

A rainbow visual effect appears across the sky

Gold coins scatter around the map (collectible for bonus Sheckles)

Pro tip: Have multiple crops planted and growing before the top of the hour. The Luck mutation applies to everything currently in the ground, so the more plants you have ready, the more Luck-mutated crops you can harvest.

---

How to Get the Luck Mutation {#luck-mutation}

The Luck mutation is exclusive to this event and works differently from regular mutations:

It is automatically applied during the Rainbow Event — you do not need any special gear or pet abilities

Luck-mutated crops have a distinctive green shimmer with clover particles

The mutation provides a 3.5x value multiplier on any crop it affects

Luck stacks with other mutations (Wet, Chilled, Chocolate, etc.) for massive value boosts

Best mutation stacking combo this week:

Luck (3.5x) + Celestial (5x) + Chocolate (2.5x) = 43.75x base value

If you can land this triple stack on a high-base-value crop like Dragonfruit or Crystal Bloom, you are looking at millions of Sheckles per harvest.

---

Four-Leaf Clover Seed Guide {#four-leaf-clover}

The Four-Leaf Clover is the crown jewel of this event — an ultra-rare seed that can only be obtained during St. Patrick's week.

How to get it:

Harvest Luck-mutated plants during the Rainbow Event

Donate them to one of the three pots around the map

Each pot shows the reward you receive once you meet the donation quota

After donating three Luck-mutated plants, there is a small chance of receiving a Four-Leaf Clover seed

Four-Leaf Clover stats:

Grows in approximately 8 minutes

Base value: ~15,000 Sheckles

Has an increased chance of receiving rare mutations when harvested

The harvested crop itself has a permanent luck aura (cosmetic)

Current trade value: Four-Leaf Clover seeds are trading for 200,000-350,000 Sheckles due to their extreme rarity. If you manage to get one, consider holding — these are limited-time and values will only climb after the event ends.

Smithing Event: Crafting System {#smithing-event}

The Smithing Event introduced an entirely new progression mechanic: crafting. Players can now forge seeds, gear, and pets using materials gathered from gameplay.

How Crafting Works

Visit the Smithing Station (new building near the garden plots)

Select a crafting category: Seeds, Gear, or Pets

Combine the required materials

Wait for the forging timer (varies by item rarity)

Collect your crafted item

Crafting Materials

Iron Ore — Harvested from special ore nodes that spawn around the map

Gems — Obtained from the new Gem Egg or by harvesting gem-mutated crops

Essence — Dropped by releasing pets or deconstructing duplicate gear

Event Tokens — Earned through event participation and daily quests

---

Seed, Gear & Pet Crafting {#crafting-guide}

Seed Crafting

Combine common seeds with materials to create higher-rarity seeds:

3 Common Seeds + 5 Iron Ore = 1 Uncommon Seed

3 Uncommon Seeds + 10 Iron Ore + 2 Gems = 1 Rare Seed

3 Rare Seeds + 20 Iron Ore + 5 Gems + 1 Essence = 1 Epic Seed

Gear Crafting

Forge powerful new gear at the Smithing Station:

Iron Watering Can — 15 Iron Ore (1.5x water efficiency)

Gem-Studded Shears — 10 Iron Ore + 3 Gems (faster harvest speed)

Golden Trowel — 25 Iron Ore + 8 Gems + 2 Essence (increases mutation chance by 10%)

Pet Crafting

The most exciting addition — craft pets by fusing materials:

Forge Pup — 20 Iron Ore + 5 Gems (Common, auto-water ability)

Crystal Fox — 30 Iron Ore + 10 Gems + 3 Essence (Rare, mutation chance boost)

Ember Drake — 50 Iron Ore + 20 Gems + 10 Essence (Epic, 2x harvest value aura)

---

Gem Egg Breakdown {#gem-egg}

The Gem Egg is a new egg type introduced with the Smithing update. It costs 50,000 Sheckles and contains gem-themed pets:

The Celestial Golem is the chase pet of this update. With a 0.5% hatch rate, expect to spend approximately 10 million Sheckles on average to hatch one. Current trade value sits around 2-3 million Sheckles.

FAQ {#faq}

When does the St. Patrick's Day event end?

The event started March 14 and runs for one week, ending approximately March 21, 2026. Log in before then to get your Luck-mutated crops and Four-Leaf Clover seeds.

Can I get the Luck mutation outside of the Rainbow Event?

No. The Luck mutation is exclusive to the hourly Rainbow Event during the St. Patrick's week. It cannot be obtained through gear, pets, or weather.

Is the Smithing system permanent or temporary?

The Smithing Station and crafting system are permanent additions to the game. However, some crafting recipes may rotate or change with future updates.

What is the best pet from the Gem Egg?

The Diamond Dragon offers the most practical value with 2x crafting material drops. The Celestial Golem is the rarest and most valuable for trading, but the Diamond Dragon will earn you more resources over time.

Should I sell or hold Four-Leaf Clover seeds?

Hold them. Four-Leaf Clover seeds are event-exclusive and will never be obtainable again after this week. Their value will steadily increase as supply dries up. Current trade values of 200,000-350,000 Sheckles could easily double within a month.

When is the next Grow a Garden update?

The next update is scheduled for Saturday, March 21, 2026 at 1 PM ET / 10 AM PT. The developer has teased that the team is "cooking up something big," so expect a significant content drop.
