Path of Exile 2: How to Get and Use the Prism of Belief Diamond

Path of Exile 2 is set to redefine the ARPG experience, introducing deeper mechanics, tougher bosses, and a more intricate loot system. Among the many powerful items in the game, the Prism of Belief Diamond stands out as one of the most valuable Unique Jewels. This Jewel, while not universally applicable like Against the Darkness, is an absolute game-changer for builds that can utilize it effectively.

Not only is it one of the rarest POE2 items in the game, but it also plays a significant role in maximizing DPS, especially for high-end builds looking to push their damage numbers to the extreme. However, obtaining it is no easy feat—it requires defeating Path of Exile 2's hardest boss, the Arbiter of Ash, at the highest possible difficulty. Let's dive into how to get the Prism of Belief Diamond, how it works, and why POE 2 Currency is essential for players looking to trade for this powerful item.

How to Get the Prism of Belief Diamond in PoE 2

Exclusive Drop from Arbiter of Ash at Difficulty 4

The Prism of Belief Diamond is a unique drop from the Arbiter of Ash, the most challenging boss in Path of Exile 2. This boss is infamous for its one-shot mechanics, high-damage attacks, and narrow DPS windows, making it a true test of skill and patience.

To obtain the Prism of Belief Diamond, players must defeat the Arbiter at Difficulty 4, the highest possible setting. Lower difficulties will not drop this Jewel, so preparing your character with optimized gear, resistance, and damage output is crucial before attempting this fight.

Where to Find Arbiter of Ash

The Arbiter of Ash is located in the Burning Monolith. However, before accessing this area, players need to collect three Crisis Fragments:

    Iron Crisis Fragment

    Copper Crisis Fragment

    Stone Crisis Fragment

These fragments are dropped by bosses found in three randomly generated Citadels on the Atlas. Since Citadels are hidden by the fog of war, players must navigate toward beams of light shooting into the sky, which indicate their locations. Once all three Crisis Fragments are collected, they can be used to unlock the Burning Monolith, granting access to the Arbiter of Ash.

How to Unlock Arbiter of Ash at Difficulty 4

Unlike standard boss fights, facing the Arbiter of Ash at Difficulty 4 requires multiple victories at lower difficulties. Here's how to unlock the highest difficulty:

    Defeat the Arbiter of Ash for the first time – This rewards 2 Arbiter Skill Points in the Atlas tree.

    Allocate the Arbiter Skill Points – Use them to unlock ‘+1 to Arbiter Difficulty' in the Atlas tree.

    Repeat the fight three more times – Each time, invest your Arbiter Skill Points to increase the difficulty.

    At Difficulty 4, the Prism of Belief Diamond has a chance to drop.

Only at this final level will the Prism of Belief Diamond be obtainable, making it one of the most sought-after and exclusive drops in PoE 2.

How the Prism of Belief Diamond Works in PoE 2

The Prism of Belief Diamond is highly prized for increasing the level of key skills by up to +3, a massive boost for endgame builds. This effect stacks with other +Skill modifiers, making it an essential Jewel for maximizing damage potential.

For example, consider the Spark Sorceress, one of the most powerful builds in Path of Exile 2. If a player uses a Prism of Belief Diamond with +3 to Spark Skills in a Jewel socket, then combines it with:

    A Staff that gives +7 to all Lightning Spell Skills

    A Level 21 corrupted Spark Skill Gem

They can effectively push their Spark skill to Level 31 before even factoring in additional bonuses from the Passive Skill Tree, Amulets, or Rings. The potential for insane damage scaling makes this Jewel an endgame necessity for certain builds.

Trading for Prism of Belief Diamond with POE 2 Currency

Since the Prism of Belief Diamond is an extremely rare drop, most players will obtain it through trading rather than farming. The value of this Jewel can range from 1-2 Divine Orbs to hundreds, depending on its roll and skill bonuses.

This is where POE 2 Currency becomes essential. Players who lack the ability to farm the Arbiter of Ash at Difficulty 4 can instead accumulate valuable trade currency to purchase the Prism of Belief Diamond from other players. The most effective ways to do this include:

1. Farming High-Value Items

Certain Unique items, high-level crafting materials, and other rare drops can be traded for Divine Orbs or Exalted Orbs, which are commonly used in high-end trades.

2. Currency Flipping

Some experienced traders use POE 2 Currency flipping strategies, where they buy low and sell high on items and currency exchanges. This is a riskier but profitable way to build wealth quickly.

3. Selling Services

Many top-tier players offer boss-killing services for a fee. If you can't defeat the Arbiter of Ash yourself, you might be able to hire a skilled player to kill him for you in exchange for in-game currency.

4. Running Mapping and Atlas Strategies

Focusing on running Atlas Citadels, Delve, or Heist content can be a steady way to farm POE 2 Currency, allowing you to buy high-end items like the Prism of Belief Diamond without relying on extreme boss fights.

Fixing the Prism of Belief Diamond DPS Display Bug

Some players have reported that their DPS does not update after equipping the Prism of Belief Diamond. This issue occurs because Path of Exile 2 only updates the DPS calculations when switching zones.

Solution:

    Simply teleport to another zone and check your DPS again. The new value should reflect the correct bonus provided by the Prism of Belief Diamond.

Final Thoughts

The Prism of Belief Diamond is one of Path of Exile 2's most sought-after Unique Jewels, offering unparalleled benefits for high-end DPS builds. However, obtaining it requires defeating the hardest boss at the highest difficulty, making it a challenging endeavor for most players.

For those who prefer an alternative approach, trading for the Prism of Belief Diamond using POE 2 Currency is a viable and often more efficient route. By farming valuable items, flipping currency, or utilizing in-game services, players can acquire this rare Jewel without taking on the Arbiter of Ash themselves.

Regardless of how you obtain it, the Prism of Belief Diamond remains a powerful tool in PoE 2, capable of pushing builds to their absolute limits. Whether you're a hardcore grinder or a savvy trader, this Jewel is one to keep on your radar.
