Heartopia Tool Upgrades: Complete Guide to Upgrading All Tools
Every tool in Heartopia can be upgraded four times — from Basic to Iron, Gold, and finally Diamond — at the Blacksmith in town. Each upgrade tier unlocks new abilities, larger area-of-effect actions, and reduced energy costs that fundamentally change how you play each day. This complete guide covers all 6 tools (Axe, Pickaxe, Hoe, Watering Can, Fishing Rod, and Shovel) across all 4 tiers, with exact materials, gold costs, upgrade times, and new abilities unlocked at each level, plus a recommended priority order to maximize your efficiency from Day 1.
What Is Tool Upgrading in Heartopia?
Tool upgrading is Heartopia's primary character progression system for resource gathering. Unlike crop skills or cooking, which improve through repeated use, tool power comes from deliberate investment at the Blacksmith. You bring your existing tool, the required ore bars, and the gold upgrade fee, and the Blacksmith transforms it into a more powerful version over one to three days.
Each upgrade tier corresponds to a material tier: Iron, Gold, and Diamond. Iron upgrades are affordable and unlocked relatively early (around Week 2), Gold upgrades require cave diving to Floor 5+ and cost 3,000g each, and Diamond upgrades demand the rarest ore in the game plus significant gold. The progression is intentionally gated to match your expanding capability as you explore more of the map.
The most impactful thing to understand about tool upgrades is that they do not just improve efficiency — many unlock access to entirely new content. The Iron Pickaxe opens ore floors that were literally inaccessible before. The Gold Fishing Rod enables ocean fishing with rare fish species. The Gold Shovel reveals excavation sites not visible on the default map. Upgrading tools is not optional if you want to see all Heartopia has to offer.

Recommended Upgrade Priority Order
You can only upgrade one tool at a time, and each upgrade locks you out of that tool for 1-3 days. Here is the optimal order for Iron-tier upgrades, followed by Gold-tier, to maximize your early-game progression.
1st — Pickaxe to Iron
Opens iron ore mining (Floor 3-4), which gives you the Iron Bars needed for all other Iron-tier upgrades. This one upgrade enables every other upgrade in the game. Do this on Day 5-7 after you have mined your first copper stash.
2nd — Watering Can to Iron
Waters 3 crops per use instead of 1, cutting your morning watering time by 66%. As your crop plot expands, the time savings compound dramatically. The energy saved each morning frees you for a second activity (mining or fishing). Priority upgrade for farming-focused players.
3rd — Axe to Iron
Unlocks stump clearing and boosts Wood yield by 50%. Stumps block farm expansion and high-yield lumber access. Once cleared, your farm footprint grows and you access Hardwood (needed for major building upgrades). Aim for this by Week 2.
4th — Fishing Rod to Iron
Opens river fishing and uncommon fish varieties. The Fish you catch from this point sell for 2-5x more than shallow-water commons. If fishing is a core income strategy for you, move this up to position 2. For farmers, it can wait until Week 3.
5th — Hoe to Iron
Tills 3 tiles per swing, saving meaningful time on large plots. Less urgent than the Watering Can because Sprinklers (craftable at Advanced Workbench) can automate watering, but there is no automation for tilling. Upgrade before you expand past a 5×5 plot.
6th — Shovel to Iron
Upgrades dig speed and raises relic spawn rate to 70%. Unless relic restoration is your primary focus, this upgrade is lower priority in Year 1. Move it higher if you are actively chasing Museum Stars and the relic income strategy.
Worked Example: Week 1-3 Upgrade Plan
Here is a practical timeline for getting all six tools to Iron tier in your first three weeks of play.
Farm your starter crops, chop trees for Wood, and gather Stone. Use the basic cave on Day 3 to mine Copper Ore. Smelt Copper Bars at your furnace. This is your starting capital for early upgrades.
Mine deeper — aim for Floor 2-3 to collect Iron Ore. You need 25 Iron Bars total for all six Iron upgrades (5 bars each, except Fishing Rod at 3). Smelt overnight.
Visit the Blacksmith with Pickaxe + 5 Iron Bars + 1,000g. Submit for upgrade. Tomorrow morning you get your Iron Pickaxe back.
Pick up Iron Pickaxe. Evening: submit Watering Can + 5 Iron Bars + 1,000g. Spend Day 7 doing non-watering tasks (fishing, socializing, cave diving with the new Pickaxe).
Collect Iron Watering Can — your farming speed is now dramatically faster. Submit Axe + 5 Iron Bars + 1,000g to Blacksmith.
Collect Iron Axe, submit Iron Rod, collect, submit Iron Hoe, collect, submit Iron Shovel. With all tools submitted sequentially, all six tools reach Iron by Day 12-14 at the cost of ~5,800g and 25 Iron Bars.
Begin targeting Gold Ore on Cave Floor 5+. The upgrade cascade to Gold tier mirrors the same sequence but costs 3,000g per tool and requires 5 Gold Bars each. Target the Watering Can and Pickaxe for Gold first — same logic as Iron tier.
Pro Tips for Tool Upgrades
📅
Upgrade Before Rest Days
Submit tools for upgrades on the evening before a rest day, festival, or rainy day. You will not miss having the tool on days you were not going to use it anyway. Never upgrade the Watering Can before a full growing week — your crops will wither without water.
🔨
Batch Smelt Before Upgrading
Smelt a large batch of Iron Bars in one go rather than trickling them through the furnace. Each furnace run (2 Iron Ore → 1 Iron Bar) takes 2 in-game hours. Load the furnace with your full ore stack before bed so all bars are ready in the morning. This prevents the "waiting for bars" bottleneck that slows your upgrade chain.
💰
Gold Upgrades Require Active Saving
Gold-tier upgrades cost 3,000g each — that is 18,000g total for all six tools, which is substantial in early-to-mid game. Set a weekly savings target of 1,000g from crop sales to fund your Gold upgrade chain. Do not spend all your gold on building upgrades until you have secured at least the Pickaxe and Watering Can at Gold tier.
💎
Diamond Requires Late-Game Planning
Each Diamond upgrade needs 2 Diamonds and 3 Gold Bars, or 1 Diamond + 3 Gold Bars (for the Fishing Rod). Diamonds are found on Cave Floor 8+ and are rare even with a Gold Pickaxe. Do not rush Diamond upgrades — they are Year 2+ goals for most players. Prioritize the Watering Can for Diamond first; its self-refilling and 5×5 area transforms late-game farming.
Frequently Asked Questions
Where do I upgrade tools in Heartopia?
All tool upgrades are handled by the Blacksmith NPC, whose shop is on the east side of town. You can visit the Blacksmith on any day the shop is open (closed on Tuesdays and holidays). Hand over your tool and the required materials, pay the gold cost, and the Blacksmith will have your upgraded tool ready the next morning. You cannot use the tool while it is being upgraded, so plan upgrades for the evening before a non-farming day.
Can I upgrade tools at my workbench or does it have to be the Blacksmith?
Tool upgrades are exclusive to the Blacksmith — you cannot upgrade tools at your workbench. The workbench is used for crafting items like Sprinklers and Bee Boxes, not tool modifications. The one exception is the Fishing Rod: you can craft Fishing Lures at the workbench to add temporary buffs, but the rod itself must still be upgraded at the Blacksmith for its permanent stat increases.
What is the most important tool to upgrade first in Heartopia?
The Pickaxe to Iron should be your first upgrade. Mining Iron ore with the Iron Pickaxe gives you Iron Bars, which are the crafting material for every other Iron-tier upgrade (Axe, Hoe, Watering Can, Fishing Rod, Shovel). One good cave run after the Pickaxe upgrade typically nets enough Iron Bars for 2-3 additional Iron-tier upgrades immediately after. Prioritizing the Pickaxe creates a cascade of unlocks.
How long does each tool upgrade take at the Blacksmith?
Iron-tier upgrades take 1 in-game day (tool ready next morning). Gold-tier upgrades take 2 days. Diamond-tier upgrades take 3 days. During the upgrade period, you will not have access to that tool, so avoid upgrading critical tools (Watering Can, Pickaxe) right before a high-yield day. Submit upgrades the evening before a rest day or festival day when you have less need for that specific tool.
Is the Diamond tier worth it, or is Gold tier enough?
For most tools, Gold tier is sufficient for 90% of gameplay. Gold Pickaxe accesses Floor 5+ gold ore; Gold Watering Can covers a 3×3 crop area; Gold Axe handles large trees. Diamond tier is most impactful for the Watering Can (self-refilling, 5×5 coverage) and the Fishing Rod (legendary fish access). Diamond Pickaxe is valuable for completionists wanting Floor 8+ content. Diamond Shovel is niche — only needed if you are chasing every Museum relic.
What happens if I give the Blacksmith the wrong tool by mistake?
You will get a confirmation dialogue before the Blacksmith begins any upgrade, showing the tool, materials consumed, gold cost, and time required. Review this carefully before confirming. If you cancel before confirming, you keep your materials. Once you confirm and the upgrade begins, there is no cancellation — the materials are consumed and the upgrade runs to completion. The game does not allow simultaneous upgrades; the Blacksmith handles one tool at a time.
Do tool upgrades affect energy consumption?
Yes. Higher-tier tools reduce the energy cost per use for most actions. An Iron Axe costs 2 energy per tree chop versus 4 for the Basic Axe. By Gold tier, energy cost per use is typically 50% of Basic tier. The Diamond Watering Can self-refills and its 5×5 area means fewer total swings per field, making it the single biggest energy saver in the game. Over a full season, Diamond tools effectively extend your daily productive hours significantly.
