For Tarnished seeking to transcend their mortal limitations and wield arcane power akin to a deity, the Cerulean Hidden Tear in Elden Ring remains a coveted prize even years after the game's release. This potent Crystal Tear, when mixed into the Flask of Wondrous Physick, grants a staggering 15 seconds of unlimited Focus Points (FP), effectively removing all mana constraints for a brief but glorious window. This effect empowers spellcasters to unleash devastating, continuous barrages of sorceries or incantations, turning formidable bosses into mere memories. The journey to obtain this tear, however, is a trial in itself, requiring adventurers to brave the treacherous slopes of Mt. Gelmir and best a grotesque guardian.

Locating the Cerulean Hidden Tear

The quest for the Cerulean Hidden Tear begins in the volcanic region of Mt. Gelmir. The primary objective is to defeat a specific Ulcerated Tree Spirit that guards the tear. The most straightforward path starts from the Road of Iniquity Site of Grace. From this checkpoint, Tarnished must journey northeast along the road. The landscape is dominated by a massive Minor Erdtree, at the base of which lies a small enemy encampment. The boss arena and the target itself are situated directly beneath the sprawling roots of this great tree.

For those who have not yet unlocked the Road of Iniquity Site of Grace, the ascent to Mt. Gelmir is an adventure in navigation. The route typically begins from the western bridge in the Altus Plateau that connects to the mountain's base. The path involves a series of precarious climbs using ladders and traversing narrow, rocky bridges—a task where the spectral steed, Torrent, proves invaluable. Notably, this initial trek to the grace site does not require confronting any mandatory bosses, allowing players to focus on the upcoming challenge.

Strategies for Defeating the Ulcerated Tree Spirit

The Ulcerated Tree Spirit is a terrifying sight: a writhing, serpentine mass of roots and bark that fills its cramped arena. Its aggressive, sweeping attacks can quickly overwhelm unprepared challengers. The key to victory lies not in panic, but in calculated aggression and positional awareness.

Core Combat Tactics:

  • Maintain Composure: The creature's movements, while powerful, are often slow and telegraphed. Patiently timing dodges is far more effective than frantic rolling.

  • Optimal Positioning: A highly effective strategy is to cling to the boss's left side (the player's right). From this vantage point, many of its most dangerous area-of-effect thrashing attacks will miss. The primary threat from this position is its left-arm swipe, which has a distinct, winding wind-up animation, allowing for a well-timed dodge or block.

  • Exploit Elemental Weakness: This arboreal horror is particularly susceptible to fire damage. Incantation users should equip spells like Flame Sling or Flame of the Fell God, while melee builds can apply fire grease to their weapons or utilize fire-based Ashes of War for significant bonus damage.

Phase Transition Alert: When the Ulcerated Tree Spirit's health is reduced to approximately half, it will erupt in a burst of golden, holy flames. This signifies the start of its second phase.

  • All its subsequent physical attacks now carry additional Holy damage.

  • It gains access to a powerful explosive transition attack that it can reuse.

  • Shield users should note that unless their shield has high Holy damage negation, they will suffer chip damage through blocks.

The fundamental strategy remains consistent in Phase Two, but the margin for error shrinks due to the increased damage output.

Mastering the Cerulean Hidden Tear's Power

Once the Ulcerated Tree Spirit is felled and the Cerulean Hidden Tear is claimed, its true potential can be unlocked at any Site of Grace. By selecting the "Mix flask of Wondrous Physick" option, players can combine two Crystal Tears. The Cerulean Hidden Tear should be one of them. The choice of the second tear is crucial for maximizing the combination's destructive potential.

Recommended Synergistic Tear:

The Magic-Shrouding Cracked Tear is arguably the perfect partner. When consumed, it boosts all magic damage by 20% (adjusted to 12.5% in player-versus-player combat) for a full three minutes. This duration vastly outlasts the Cerulean Tear's 15-second FP effect, ensuring your spells hit with maximum force during your unlimited casting window.

Iconic Builds and Spell Combinations:

With the Flask mixture prepared, consuming it from the item menu activates both effects simultaneously. For 15 seconds, the caster becomes an unstoppable artillery piece. The most famous and devastating application of this power is with the sorcery Comet Azur.

  • The "Unlimited Beam" Combo: By drinking the Physick and then casting Comet Azur, a player can channel the spell's massive, continuous beam of glintstone energy for the entire 15-second duration without any FP drain. This can often delete a boss's health bar before they can even move.

  • Versatile Applications: The tear's utility extends beyond just sorceries. It allows for:

  • Spamming high-cost Incantations like Ancient Dragons' Lightning Strike or Ekzykes's Decay.

  • Unlimited use of powerful Ashes of War with FP costs, such as Bloodhound's Step for evasion or Royal Knight's Resolve for melee burst damage.

  • Relentless summoning of Spirit Ashes without FP concern.

Strategic Considerations and Legacy

While the Cerulean Hidden Tear offers a monumental power spike, strategic use is key. The 15-second window is brief, so positioning and timing the Flask consumption are critical—ideally just as a boss enters a vulnerable or stationary phase. It transforms difficult encounters, making it a cornerstone of many "boss melt" builds popular within the Elden Ring community.

As of 2026, the Cerulean Hidden Tear continues to be a testament to FromSoftware's design philosophy, rewarding exploration and conquest with tools that can reshape the player's approach to the game's greatest challenges. It remains a symbol of magical supremacy in the Lands Between, a fleeting taste of true omnipotence for any Tarnished bold enough to claim it.
