Where to Get Sulheart in StarRupture

Surviving on Arcadia-7 means staying on top of your health, hunger, thirst, and energy meters. The last thing you want is to collapse from starvation or dehydration right after discovering something valuable miles from your base. Consumables keep you alive during long expeditions, and Sulheart is one of the most versatile ingredients for crafting them in StarRupture.

Here’s the catch: Sulheart is one of the most dangerous plants to harvest. It only grows in sulfur fields—toxic zones filled with corrosive gas that rapidly damages your health. This creates a frustrating paradox where you need corrosion protection to safely farm the ingredient that helps you craft corrosion protection. Let me walk you through how to get Sulheart safely and what you can do with it once you’ve gathered enough.

Where to Find Sulheart in StarRupture

Sulheart grows exclusively in sulfur fields—toxic areas scattered across Arcadia-7’s surface. These fields are easy to spot thanks to their distinctive bright yellow ground and the noxious gas constantly rising from them.

Identifying Sulfur Fields

Visual cues:

• Large patches of bright yellow terrain
• Visible gas emissions rising from the ground
• Distinct contrast with surrounding landscape
• Often marked on your map in bright yellow once discovered

If you’ve been exploring systematically and unlocking your map, any sulfur deposits you’ve discovered will be permanently marked in bright yellow, making them easy to relocate for farming runs.

You’ll also find Sulfur ore deposits in these same fields, so if you need both Sulheart and Sulfur, you can knock out two objectives in one dangerous trip.

The Corrosion Problem

Here’s why Sulheart is so tricky to harvest: the sulfur fields emit corrosive gas that builds up rapidly when you enter them. Let that corrosion go unchecked, and it starts chipping away at your health bar. This means you’re on a timer the moment you step into a sulfur field.

Early-Game Farming Strategy (No Corrosion Protection)

If you haven’t unlocked corrosion resistance yet, you’ll need to use the hit-and-run method:

1. Prepare healing items before approaching the field
2. Sprint into the sulfur field at full health
3. Grab Sulhearts as quickly as possible
4. Sprint back out before corrosion damage becomes critical
5. Heal up using your medtool or consumables
6. Repeat until you’ve gathered enough

This method is inefficient and dangerous, but it’s your only option early on. The good news? You only need to gather about 25 Sulhearts once to unlock the Corrosion Resistance Plasm recipe, after which farming becomes much easier.

Mid-to-Late Game Farming (With Corrosion Protection)

Once you’ve unlocked the Corrosion Resistance Plasm recipe (which ironically requires Sulhearts), farming becomes significantly safer. Pop a Plasm before entering sulfur fields, and you’ll have 10 minutes of doubled corrosion resistance—more than enough time to gather a substantial supply.

Check out our detailed guide on how to increase corrosion resistance for the full breakdown on crafting and using this essential consumable.

What to Bring for Sulheart Farming

Don’t venture into sulfur fields unprepared. Here’s what I recommend bringing:

Essential items:

• Fully charged medtool for emergency healing
• Health-restoring consumables as backup
• Toxicity-reducing items if you have them
• Adequate inventory space to carry your haul

Optional but helpful:

• Corrosion Resistance Plasm if you’ve already unlocked it
• Energy-boosting consumables from Serpent Root for faster sprinting
• Upgraded weapons in case enemies are nearby

What Are Sulhearts Used For?

Sulhearts appear in a wide variety of consumable recipes at your Food Station. Unlike Serpent Root, which focuses primarily on energy buffs, Sulheart recipes cover the full spectrum of survival needs—though they tend to add toxicity as a side effect.

All Sulheart Recipes

Here’s every consumable you can craft using Sulheart:

Best Sulheart Consumables by Situation

Not all of these recipes are equally useful. Here are my top recommendations:

Corrosion Res Plasm (Highest Priority)

This should be the first Sulheart recipe you unlock and craft. It solves the Sulheart farming problem by letting you safely enter sulfur fields without taking constant damage. You’ll need Glowcaps from underground caves to craft it, but it’s absolutely worth the effort.

Energy Stim Shards (Best for Exploration)

Doubling your energy limit for an entire hour makes this perfect for long-distance expeditions. You’ll need Serpent Root alongside Sulhearts, but the result is the best stamina buff in the game. Essential when exploring distant areas or running from monolith-spawned enemies.

Health Shards (Emergency Healing)

With +80 HP, Health Shards provide the strongest instant healing available from consumables. The +40 toxicity is a drawback, but when you’re in danger of dying, that doesn’t matter. Keep a few of these on your hotbar for emergency situations, especially during difficult fights like beating Goliath.

Sulbon (Tank Build)

Increasing your max HP by 25% for 20 minutes is excellent for combat-heavy situations. If you’re about to tackle a difficult area or defend your base from monolith waves, pop a Sulbon beforehand for extra survivability.

Antidote Shards (Toxicity Reset)

These are your toxicity management tool. +60 HP and -40 toxicity is solid, though it removes all positive effects, so only use these between expeditions—not during active exploration when you need those buffs active.

Managing Sulheart Toxicity

Almost every Sulheart consumable adds toxicity. Here’s how to manage it:

Don’t stack multiple buffs unnecessarily: Each consumable adds toxicity, and stacking them can quickly push you into dangerous territory. Choose one or two buffs that complement each other rather than popping everything at once.

Use Antidote Shards as a reset: When your toxicity gets too high, consume Antidote Shards to reduce it. Just remember this wipes all positive effects, so do this back at base between expeditions, not in the field.

Plan your consumable timing: If you know you’re going on a long expedition, decide which buffs you actually need and stick to those. Energy Stim Shards + Corrosion Res Plasm is a solid combo that won’t overload your toxicity too much.

Sulheart Farming Tips

Unlock Corrosion Res Plasm ASAP: This single recipe transforms Sulheart farming from dangerous to manageable. Make this your priority.

Farm in bulk: Once you have corrosion protection, gather as much Sulheart as you can carry in one trip. The fewer times you need to revisit sulfur fields, the better.

Mark all sulfur fields on your map: Every time you discover a new sulfur deposit, note its location. The more fields you know about, the easier it is to farm efficiently without traveling across the entire map.

Combine with Sulfur farming: If you need both Sulfur ore and Sulhearts, gather them during the same trip to maximize efficiency.

Bring extra storage: Consider upgrading your inventory or bringing cargo containers if you’re planning a major farming session.
