If you're flying in EVE Online and not using rigs, you're leaving performance—and ISK—on the table. Rigs are permanent ship modifications that give you a serious edge, whether you're running Abyssal Deadspace in a Gila, mining dark ochre in a Mackinaw, or hunting targets in null-sec with your corporation. Think of them as the final, crucial layer of fitting that lets you fine-tune your ship for a specific role, but with one big catch: once installed, they can't be removed without destroying the rig itself. This guide cuts through the complexity and shows you, the capsuleer, exactly how to use rigs to dominate in PvE, PvP, and industry.
What Are Rigs and How Do They Work?
Rigs are special modules that go into dedicated rig slots on your ship, separate from your high, mid, and low slots. Every ship has at least one rig slot, with most having three. Their power comes from significant, passive bonuses, but they also come with a penalty, usually to a related attribute. For example, a 'Drone Speed Augmentor' rig might boost your drone velocity by 20% but also increase your drone control range penalty by 25%. You can't just swap them out in space; fitting a new rig destroys the old one. This makes planning your rig setup a strategic decision, especially for expensive ships.
Understanding Rig Size: Small, Medium, and Large
Rigs come in three sizes that correspond to ship classes. You can fit a small rig on any ship, but it's inefficient. The rule is simple: fit the rig size that matches your ship class. Frigates and destroyers use Small Rigs. Cruisers, battlecruisers, and industrial ships use Medium Rigs. Battleships, freighters, and capital ships use Large Rigs. Fitting a smaller rig on a larger ship gives a drastically reduced bonus, so it's almost never worth it. Always match the size.
Top Rig Setups for Common US Player Activities
Your rig choice defines your ship's purpose. Here are concrete setups players are using right now.
For High-Sec Mission Running and Abyssal Deadspace
If you're blitzing L4 missions in a Marauder or facing the lightning-filled rooms of Abyssal space, tank and application are key. A common setup for a Praxis battleship running Gamma sites is two 'Large Capacitor Control Circuit I' rigs for better capacitor stability against neuts, paired with a 'Large Semiconductor Memory Cell I' for faster module cycling. For shield-tanked pirate cruiser PvE, like the Gila, two 'Medium Core Defense Field Purger I' rigs are standard to boost passive shield regeneration, letting you run sites with less downtime.
For Null-Sec and Low-Sec PvP
PvP rigs are all about amplifying your engagement profile. For a brawling HAC like the Sacrilege, 'Medium Anti-Explosive Screen Reinforcer I' rigs can harden your armor tank against your enemy's chosen damage type. Tackle frigates like the Crucifier often use 'Small Auxiliary Thrusters I' to increase their signature radius penalty but gain crucial speed to catch targets. Logistics pilots swear by 'Medium Capacitor Control Circuit I' rigs to keep their remote repair modules running indefinitely during a fleet fight.
For Mining and Industry
Miners live and die by yield. On a Skiff or Covetor, you'll see 'Medium Mining Laser Field Enhancement I' rigs to directly boost ore output per cycle, despite the CPU penalty. For ice mining in a Prospect, 'Medium Ice Harvester Accelerator I' rigs cut cycle time dramatically. Industrialists moving goods use 'Medium Hyperspatial Velocity Optimizer I' rigs on their Deep Space Transports to slash warp speed time, making high-risk routes slightly less dangerous.
The Real Cost: Materials, Skills, and the Fitting Penalty
Rigs aren't free. Tech I rigs are built from basic materials like Tritanium and Pyerite, but Tech II and faction rigs require rare materials from data/relic sites or moon mining. The skill Rigging is essential—it reduces the negative penalties of all rigs by 10% per level. At Rigging V, you cut those nasty side effects in half. Don't overlook the fitting penalty! Rigs increase your ship's CPU or Powergrid requirements for *other* modules. A common mistake is finishing a fit, adding rigs, and then finding you can't activate your armor repairer because your PG is now insufficient. Always fit rigs last.
Where to Buy Rigs and How to Install Them
You can buy rigs from the market in major trade hubs like Jita, Amarr, or Dodixie. To install them, right-click your ship in the fitting window, select 'Show Fitting Slot Layout,' and drag the rig into an empty rig slot. A warning will pop up reminding you it's a permanent change. Once you confirm, it's installed. To remove it, you simply drag a new rig onto the old one, which destroys the original. There's no 'uninstall' button.
FAQ
Can you remove a rig without destroying it?
No. Once a rig is installed into a slot, it is permanently attached to that ship. The only way to get rid of it is to replace it with another rig, which destroys the original one. This is why planning and committing to a ship's role is so important with rigs.
What's the difference between Tech I and Tech II rigs?
Tech II rigs provide a larger bonus than Tech I rigs but also come with a more severe negative penalty. They also cost significantly more, often requiring rare components to manufacture. The upgrade is worth it for dedicated end-game ships, but for a disposable PvP frigate or a beginner's mission runner, Tech I rigs are a perfectly cost-effective choice.
How many rig slots does my ship have?
It varies by ship. Most standard combat and industrial ships have three rig slots. Some specialized ships, like certain freighters or tech III cruisers in a specific mode, may have more or less. You can always check by looking at the ship's 'Show Info' window under the 'Attributes' tab.
Should I rig my first frigate?
Probably not with anything expensive. For your very first ships, the cost of even basic rigs might exceed the value of the ship itself. It's better to learn the basics of fitting with regular modules first. Once you're flying more advanced destroyers or cruisers and have a stable ISK income, then start experimenting with cheap Tech I rigs to see how they affect your performance.
What are "Rig Slot 6" and "Rig Slot 7" upgrades I see on the market?
Those are not rigs. They are Subsystem modules for Tech III Strategic Cruisers (T3Cs). T3Cs have a unique fitting system where you choose subsystems that determine the ship's role and bonuses. These subsystems occupy slots labeled similarly to rig slots, but they are swappable modules, not permanent rigs. Don't buy them by accident for a standard ship.
