How To Use Purity in Risk of Rain 2

Among the vast arsenal of items in Risk of Rain 2, Lunar items stand out for their high-risk, high-reward nature. These powerful artifacts offer a tremendous boost to your capabilities while imposing a significant drawback, forcing survivors to make strategic choices. One of the most debated Lunar items is Purity, a tool that can redefine a character's playstyle. This comprehensive guide will break down everything you need to know about Purity, from how to acquire it to mastering its unique mechanics for a powerful cooldown-focused build.

What is Purity and How Does It Work?

Purity is a Lunar item designed for players who want to spam their skills as quickly as possible. Its primary function is straightforward yet incredibly powerful:

• The Benefit: Purity reduces all of your skill cooldowns by a flat 2 seconds. This effect stacks, meaning each Purity you collect further slashes cooldown times, allowing for incredibly rapid ability usage.
• The Drawback: Purity severely penalizes your character's "luck." It adds negative rolls to all random proc effects, making it much harder for on-hit items to activate.

This trade-off makes Purity a strategic choice rather than a straightforward upgrade.

Understanding the Purity Mechanic: The Luck Penalty Explained

To use Purity effectively, you must fully grasp its negative effect. The item doesn't just lower your luck; it actively works against your proc-chance items.For any item with a percentage-based chance to activate (like a Tri-Tip Daggers' 15% chance to bleed), Purity adds an additional negative roll. The game must now succeed on multiple rolls for the effect to trigger.

• With 1 Purity: A 10% chance item requires two successful 10% rolls, effectively reducing the chance to a mere 1% (0.10 * 0.10 = 0.01).
• With More Stacks: Each additional Purity adds another negative roll. Two Purity items would require three successful rolls, making proc-based builds nearly impossible.

This makes items like Ukulele, AtG Missiles, and Shatterspleen dramaticallyless effective. However, it has no impact on items with guaranteedeffects, such as Soldier's Syringes or Lens-Maker's Glasses (until youreach 100% critical chance).

How to Acquire Purity in Risk of Rain 2

Obtaining Purity follows the same path as most Lunar items. You have two primary methods:

The Bazaar Between Time: Use a Newt Altar on any stage to open a portal to this special shop.Here, you can directly purchase Purity for a set cost in Lunar Coins.

Lunar Pods: Scattered throughout the stages are Lunar Pods that cost one Lunar Coin to open. These pods contain a random Lunar item, offering a chance toobtain Purity through luck.

Optimal Builds: Who Should Use Purity?

Purity is not for every character or build. Its value is highest on survivorswho rely more on their innate skills than on proc-on-hit items.

Top Characters for Purity:

• Loader: Loader's power comes from her high-damage skills like Thunder Punch and Knuckleboom. Purity allows her to use these devastating attacks farmore frequently, turning her into an unstoppable brawler.
• Artificer: With Purity, the Artificer can maintain near-permanent uptime on herpowerful Flamethrower ability, melting bosses and hordes of enemies with constant high damage.
• Mercenary: Mercenary thrives on mobility and using his skills in quick succession. Reduced cooldowns on Eviscerate and Blinding Assault make him even more elusive and deadly.

Items to Pair with Purity:
Focus on items that provide direct stat increases or guaranteed effects. Soldier's Syringe, Lens-Maker's Glasses, Paul's Goat Hoof, and Energy Drink are all excellent choices, as they are unaffected by the luck penalty. Gesture of the Drowned is a particularly powerful synergy for equipment-based builds, as itfurther reduces equipment cooldown without being impacted by Purity'sdownside.

Final Verdict: Is Purity Worth It?

Purity is a niche but incredibly powerful item when used correctly. If you are playing a skill-dependent character and are willing to forgo aproc-based build, stacking Purity can create one of the most potent andfun playstyles in Risk of Rain 2. Understand the risk, build around thereward, and you'll unlock a new level of power.
