Artifact of Glass Risk of Rain 2

Artifact of Glass

Allies deal 500% damage, but have 10% health. The Artifact of Glass is the ultimate glass cannon modifier. One-shot protection is disabled - a single hit from any enemy can kill you outright. In exchange, you obliterate everything in seconds. The code is all nine diamonds, the simplest pattern in the game. It is not the same as the Shaped Glass Lunar item.

A Moment Fractured Risk of Rain 2
Code Location: A Moment, Fractured

Behind the Obelisk on the final island. Reach via the Celestial Portal - loop once, hit Stage 3, complete the teleporter event.

Reaching A Moment, Fractured

You need to loop at least once first. On Stage 3 of any subsequent loop (Stage 8, 13, 18...) a Celestial Orb appears around the teleporter. Complete the teleporter event and a Celestial Portal spawns. Enter it, navigate the floating islands down to the Obelisk, and look behind it for the code tablet.

How It Works

500% Damage

All allies deal 5x their normal damage. Applied after all other damage calculations. Every item, proc, and skill benefits.

10% Health

All allies have 10% of their normal max HP. A survivor with 100 base HP now has 10. Even one hit from most enemies is lethal.

One-Shot Protection Disabled

Normally, no single hit can reduce your health below 10% of max. Glass disables this entirely. A single attack can kill you from full health.

Infusion Changed

Infusion's health gain changes from +1 HP per kill to +0.1 HP per kill (1 HP per 10 kills). Stacking HP is nearly useless with Glass active.

Umbrae Unaffected

Artifact of Vengeance doppelgangers are not part of the ally team. Their damage and health are unchanged by Glass.

Enemies Unaffected

Only the player team is affected. Enemy health and damage are identical to a normal run.

One-Shot Protection Is Completely Off

Normally a single damage instance cannot reduce you below 10% of max HP. With Artifact of Glass your max HP is already 10% of normal - and protection is gone. This means any attack dealing more damage than your tiny health pool kills you instantly, regardless of how many HP items you have.

Artifact of Glass vs Shaped Glass

Frequently confused. These are two completely separate things that happen to share a name theme.

Best Survivors for Glass

Mercenary
Dodge-based evasion means you can avoid most hits. High burst DPS maximized by 5x multiplier. Strong Glass pick.
Loader
High base damage + Glass = one-shotting most enemies. Short range is offset by massive burst on contact.
Artificer
Already burst-focused. Glass turns her M1 into a screen-clearing cannon. Hover ability helps dodge.
Railgunner
Long range keeps you safe. Sniper shots deal obscene damage with Glass. Strong and survivable pick.
Huntress
High mobility via blinks helps avoid hits. Good burst with Glass, but fragile at close range.
Acrid
Relies on poison DoT which doesn't benefit as much from flat damage multipliers. Melee range is extremely dangerous with 10% HP.

Best Combos

Glass + Command

The classic. Command lets you choose every item to maximize damage synergy. No RNG means every drop builds toward your chosen DPS setup.

Glass + Sacrifice + Command

Full triple combo. Monster drops become chosen Command Essences, every one selected for damage amplification. Fastest run win condition.

Glass + Metamorphosis

Random survivor each stage with 5x damage. Some survivors thrive with Glass (Mercenary, Loader, Artificer), others struggle. High variance, high fun.

Glass alone

Still extremely viable. Prioritize mobility and range. Burst everything before it touches you. Faster clears mean fewer windows for lethal hits.

Glass + Chaos

Friendly fire is dangerous enough normally. With 10% HP, your own explosions (Brilliant Behemoth, Kjaro's Band) are instant death. High risk, high laugh factor.

Glass + Death

When one player dies everyone dies - combined with Glass's 10% HP, a single stray hit ends the entire team. Only for full communication co-op runs.

Tips

Kill before being killed. Glass runs are decided in the first second of every encounter. Burst everything from range or before it can attack. Speed and aggression win.
Prioritize movement items. Hopoo Feathers, Paul's Goat Hoof, Energy Drink, Mocha - anything that keeps you out of reach. Dead enemies can't hit you.
Armor items still help. Repulsion Armor Plate, Tougher Times - anything that reduces flat damage gives you more buffer on your 10% HP. Every point matters.
Dio's Best Friend is essential. One free death from full health is enormous when every hit is potentially lethal. Prioritize it early.
Watch your own explosions. Items like Brilliant Behemoth, Kjaro's Band, and Sticky Bomb deal self-damage that bypasses your tiny HP when friendly fire is involved.
Eclipse difficulty with Glass is extremely challenging. Eclipse reduces healing by 50% per level - combined with 10% HP, even passive regeneration barely matters. Expect frequent deaths.

Frequently Asked Questions

What does the Artifact of Glass do in Risk of Rain 2?

The Artifact of Glass makes all allies deal 500% damage but reduces their max health to 10%. One-shot protection is disabled, meaning a single hit can kill you from full health. It is the ultimate glass cannon modifier - you kill everything instantly but die just as fast.

What is the Artifact of Glass code?

The Artifact of Glass code is ♦♦♦ ♦♦♦ ♦♦♦ - all nine symbols are Diamonds. It is the easiest artifact code to remember. The code tablet is found in A Moment, Fractured, behind the Obelisk on the final floating island.

Where is the Artifact of Glass code?

The code is in A Moment, Fractured - the hidden realm accessed via the Celestial Portal. Loop at least once, reach Stage 3, complete the teleporter event, and enter the Celestial Portal. Navigate down the floating islands to the Obelisk and look behind it for the stone tablet showing all diamonds.

Is the Artifact of Glass the same as Shaped Glass?

No. They are different things. The Artifact of Glass is a run modifier (toggle in lobby, affects all allies, 500% damage at 10% health). Shaped Glass is a Lunar item (purchasable at the Bazaar, affects only the holder, doubles damage per stack while halving health per stack). Both disable one-shot protection but work independently.

Does one-shot protection work with Artifact of Glass?

No. One-shot protection is explicitly disabled while the Artifact of Glass is active. Normally no single hit can deal more than 90% of your max HP, but Glass removes this safety net entirely. Any hit that exceeds your 10% health pool kills you instantly.

What survivors work best with Artifact of Glass?

Survivors with strong evasion or long range work best. Mercenary's dodge rolls, Loader's burst damage, Artificer's hover, and Railgunner's range all let you take advantage of the 5x damage while staying out of lethal range. Avoid melee survivors that stay in close range without strong survivability tools.
