InElden Ring, players will have to contend with the Lands Between’s countless dangers, and make use of a variety of tools to do so. These come in many forms, including weapons, armor, and spells. One valuable tool in any player’s arsenal, regardless of their preferred build, is the Physik Flask.

Elden Ring’s Physik Flask is a special potion that is refilled whenever players rest at a Site of Grace, but unlike the Flasks of Crimson and Cerulean Tears, this flask’s effect is not set in stone. The Physik Flask instead allows players to customize its effects by placing up to two “Crystal Tears” inside it. Each of these Tears offers a different effect, allowing players to create a flask that suits their playstyle and provides whatever benefits they find most valuable.

The Physik Flask and Crimson Crystal Tears

The Physik Flask itself can be found alongside the Crimson Crystal Tearat the Third Church of Marika, in Limgrave. TheCrimson Crystal Tearrestores 50% of the player’s HP when the Physik is used, making it a potent healing option. A second Crimson Crystal Tear can be acquired in the Capital Outskirts, guarded by some enemies beneath a Minor Erdtree.

The Crimson Crystal Tears stack, and can be used to create a Physik Flask that always fully heals the player when used, if desired. This makes for a fantastic panic button if players are venturing into particularly dangerous locales.

Greenspill Crystal Tear and Spiked Cracked Tear

This pair of Crystal Tears can be acquired by heading south from the Third Church of Marika in Limgrave, into the Mistwood region. A Minor Erdtree towers here, and a basin at the foot of the tree will yield both Tears when found.

The Greenspill Crystal Tear boosts the player’s maximum stamina, which is incredibly useful for stamina-hungry builds, such as builds using heavy weapons. The Greenspill Crystal Tear is also useful to provide some extra wiggle room for players who find themselves overextending and burning through their stamina too quickly.

The Spiked Cracked Tear is a fantastically powerful tool that enhances the potency of charged attacks. Since Charged Attacks are nearly universally beneficial when fighting strong foes, allowing players to stagger enemies and open them up to critical attacks, this Tear can prove tremendously helpful. It is particularly useful when using heavy weapons to give them extra kick.

Crimsonburst Crystal Tear and Opaline Bubbletear

This pair of Crystal Tears is found by traveling to the Minor Erdtree in the Weeping Peninsula and slaying the Erdtree Avatar that guards it. Erdtree Avatars are incredibly vulnerable to fire, which can be used to tear through their health at incredible speed. As such, players with the requisite faith might want to use incantations like Catch Flame to defeat the Erdtree Avatar more easily.

The Crimsonburst Crystal Tear provides the player with a health regen effect, restoring 7HP per second for 3 minutes. While this sounds like a small amount, it can make a huge difference during longer combat encounters and also helps to reactivate the Ritual Sword and Ritual Shield Talismans after taking a hit.

The Opaline Bubbletear is another excellent tool for enhancing player survivability, creating a protective shield that will absorb a single hit before breaking. The bubble won’t break if the attack was blocked with a shield that has 100% damage negation, allowing players to use guard counters without risking their emergency shield.

Cerulean Crystal Tears

TheCerulean Crystal Tearis the FP restoring equivalent of the Crimson Crystal Tear, instantly restoring 50% of the Player’s FP when the Physik Flask is used. Two Cerulean Crystal Tears can be found in the game, allowing players to mix a 100% FP restoring Physik Flask if desired.

The first is acquired from the Erdtree Avatar in the southwest of Liurnia of the Lakes, guarding the Minor Erdtree. Once again players should make use of fire to defeat this boss quickly and easily. The second Cerulean Crystal Tear can be found in the Mountaintops of the Giants, dropped by another Erdtree Avatar guarding a Minor Erdtree in the Eastern Mountaintops.

Ruptured Crystal Tears

The Ruptured Crystal Tears cause an explosion of Holy Damage moments after the Flask is used, damaging everything in proximity including the player. A single Ruptured Crystal Tear has a base damage of 800, a range of 2 meters, and deals 300 damage to the player. Putting two Ruptured Crystal Tears in the flask creates an explosion with a base damage of 1750, a range of 4 meters, and which deals 700 damage to the player.

The first Ruptured Crystal Tear is found alongside the Cerulean Crystal Tear in the southwest of Liurnia of the lakes, while the second is dropped by the Putrid Avatar in the Consecrated Snowfield alongside the Thorny Cracked Tear, at the Minor Erdtree.

Strength-Knot Crystal Tear

This Crystal Tear, found by heading Northeast from Stormhill Shack in Limgrave and locating a Basin near a troll, provides +10 strength while active. This can be very potent for boosting damage and meeting the stat requirements for heavy weapons, especially early in the game.

This Crystal Tear becomes less useful in the late-gameonce the strength softcap is reached, but it can still be an effective means of enhancing damage output in strength or quality builds.

Elden Ring_Weeping Peninsula_Faith-Knot Crystal Tear Location

Dexterity-Knot Crystal Tear

This Crystal Tear, located atop an island to the southwest of Boilprawn Shack, in Liurnia of the Lakes, functions identically to the Strength-Knot Crystal Tear but boosts the Dexterity Stat instead. Useful for builds that make use of dex weapons, and especially for meeting some of the higher stat requirements earlier in a playthrough, the Dexterity-Knot Crystal Tear can provide tons of extra damage before the softcap is hit.

Intelligence-Knot Crystal Tear

This Crystal Tear is found near the “Road to the Manor” Site of Grace in Liurnia of the Lakes, by heading southeast down a slope and then looping back north along a lower path. This path leads to a basin containing the tear which is guarded by some freaky hands. This Crystal Tear grants +10 Intelligence while active,making it useful for boosting the damage of Sorceriesand meeting the requirements for some of the more stat-hungry Sorceries. Since the softcap for intelligence, when determining Sorcery damage, is much higher than the softcaps for strength and dexterity, this Tear remains useful for much more of the game than the previous two tears.

Faith-Knot Crystal Tear

The final stat boost Crystal Tear can be found by heading to the Weeping Peninsula and finding the Demi-Human Forest Ruins, which are down in the forest below (and east from) the Church of Pilgrimage. After finding the ruins players can search north of the ruins to find a bowl containing this Crystal Tear, a short way down the cliff and guarded by poison flowers.Players can use this Tear for Incantationsin much the same way the Intelligence-Knot Tear can be used for Sorceries.

Greenburst Crystal Tear and Flame-Shrouding Cracked Tear

This pair of Crystal Tears can be acquired by taking down the Putrid Avatar that guards a Minor Erdtree in Caelid. Specifically, the Minor Erdtree found just to the northeast of the Smouldering Church, which can be found by taking the path from Limgrave into Caelid. Fire will ruin their day and make this fight way easier.

The Greenburst Crystal Tear enhances stamina recovery speed, providing players with more efficient stamina recovery during combat encounters and helping players to recover when overextending and using too much stamina.

Elden Ring_West Caelid Minor Erdtree

The Flame-Shrouding Cracked Tear is possibly one of the best Tears for boosting offensive power, boosting fire damage by 20% (12.5% in PVP). This makes it a must-have for any build that uses fire damage and makes Erdtree Avatars and their Putrid counterparts even easier to annihilate.
