In Diablo 4 Season 15, the gem system continues the restructuring from Lord of Hatred, further reducing the cost of upgrading high-tier gems and increasing the efficiency of gem resource acquisition. Currently, different types of Gems provide different effects in weapon, armor, and jewelry slots, while upgrading Royal, Grand, and Horadric Gems forms the core of endgame gem progression in Season 15. If your goal is to craft the highest-level Flawless Horadric Gem, the most direct approach is to first reliably acquire Royal Gems and then upgrade them step-by-step according to fixed crafting recipes. For players who want to quickly complete gem progression, Three Ancients is currently a key farming target. Three Ancients Fast Farming of Royal Gems In Season 15, efficient Royal Gem farming is based on Three Ancients encounters within Worldstone Keep. Upon entering the dungeon, there's no need to clear the numerous monsters along the way. Simply follow the walls near the entrance to find the branching paths leading to Ancients area. This area is usually located at the 10 o'clock or 2 o'clock position from the entrance, so quickly moving along one side of the wall will make it relatively easy to find your target. Once you reach Ancients area, activate the altar and defeat the three Ancients: Madawc, Korlic, and Talic. After completing the encounter, you'll receive a fixed Royal Gem reward, along with other loot. Here's a crucial farming tip: the fixed Royal Gem reward for Three Ancients does not increase proportionally with increasing torment difficulty. Therefore, if your character cannot comfortably farm T12, there's no need to sacrifice completion speed for a higher difficulty. A more sensible strategy is to choose a difficulty level where you can quickly defeat Three Ancients, improving overall Royal Gem output efficiency by shortening the time per run. For players who simply want to quickly accumulate Royal Gems, the advantage of speed farming Three Ancients lies in its clear objective, fixed route, and the fact that it doesn't require completely clearing the dungeon. From Royal Gem to Flawless Horadric Gem Once Royal Gem is ready, you can proceed with the high-tier gem upgrade process. The entire process is divided into three stages. The first stage is completed at Jeweler, and the latter two stages are completed using Amalgamation in Horadric Cube. Stage 1: Royal → Grand At Jeweler, use 10 Royal Gems of the same type to synthesize 1 Grand Gem. Stage 2: Grand → Horadric After obtaining te Grand Gem, use Amalgamation in Horadric Cube to synthesize 5 Grand Gems of the same type into 1 Horadric Gem at a 5:1 ratio. Stage 3: Horadric → Flawless Horadric Use Amalgamation recipe in Horadric Cube again to synthesize 5 Horadric Gems of the same type into 1 Flawless Horadric Gem. Therefore, the complete upgrade chain is: 250 Royal → 25 Grand → 5 Horadric → 1 Flawless Horadric This is also the most important number when planning your Royal Gem Farm. After determining the target gem type, you can calculate backwards how much Royal Gem you need to accumulate, and then arrange your farming plan according to your farming efficiency. Gems paired with Soul Splinters Jewelry slots in D4 Season 15 are no longer just for gem selection. With the addition of Soul Splinters, players need to balance the damage or resistance provided by gems with the special effects brought by Soul Splinters. Soul Splinters are special gems added in Season 15, with 8 types. They provide various special bonuses along with corresponding side effects and can be upgraded in Horadric Cube via Amalgamation. Unlike gems, the core value of Soul Splinters is not simply increasing damage or resistance, but rather enhancing the build through special effects. For example, Splinter of the Mother allows your character to freely pass through enemy bodies, inflicting vulnerability, and after a certain number of times, you will also be stunned - this effect is particularly useful for builds with high mobility and cleanse mechanics. Therefore, Season 15 gem setups shouldn't be simply understood as using the highest-level gems in all slots. A more reasonable approach is to use Flawless Horadric Gems for base stats and resistances, and Soul Splinters for the core build mechanics. With limited Jewelry slots, the number and type of Soul Splinters should be determined based on the build's purpose, and then the remaining slots should be used to supplement the required resistance or other stats. For builds aiming for endgame strength, Flawless Horadric Gems and Soul Splinters are not an either-or system, but rather should be combined as two sets of gems with different functions. Gem Trading and Resource Considerations Complete gems can be traded, so if you are missing a certain Diablo 4 Flawless Horadric Gem, you can obtain it through the trading system instead of necessarily farming it from scratch. For players planning to develop a character long-term, it's recommended to first determine the types of gems needed for your build, and then focus on crafting and upgrading those gems. Especially before crafting high-tier gems, avoid frequently changing your target type due to build adjustments. Also, high-tier gems are not suitable for indiscriminately dismantling for resource recycling. Confirming build requirements before crafting is usually more efficient than salvaging later. Summary The development of high-tier gems in Diablo 4 Season 15 can be simply understood as a clear upgrade path: Three Ancients → Royal Gem → Grand Gem → Horadric Gem → Flawless Horadric Gem Therefore, to efficiently craft Flawless Horadric Gems, the most important thing is not blindly increasing farming difficulty, but rather determining the target gem type, consistently farming Royal Gems, and planning resources according to the 250:25:5:1 quantity ratio.

In PoE 2 Patch 0.5.5, Spirit and Skill Level are among the most valuable core modifiers on many endgame amulets, making them highly sought-after on the market. If you choose to trade, a single amulet with these modifiers can be worth several Divine Orbs. You can also craft one yourself. Although the process is somewhat complicated, it can save a considerable amount of currency. Base: Absent Amulet The first thing you need is an Absent Amulet. It provides a free Spirit skill, but at the same time, it removes one prefix and one suffix. This means that when all of its modifier slots are filled, it will only have 4 modifiers instead of the 6 modifiers available on a normal amulet. The free Spirit skill, together with the -1 prefix and -1 suffix, essentially functions as its Implicit modifiers, similar to the Rarity modifier on a Gold Amulet. It grants a random Persistent Buff Skill for free. This skill would normally require 100 Spirit to be reserved, but with this amulet, you can use it without paying Spirit reservation cost. If your Absent Amulet rolls Tier 1 Spirit, which grants +50 Spirit, it effectively functions as an amulet with 150 total Spirit. This can provide a huge power boost for a wide range of builds. Absent Amulets cannot be obtained through normal drops. They are tied to Breach endgame mechanic. You need to use an Ornate Wombgift in Forms Beyond Understanding passive node on Genesis Tree within endgame Breaches to obtain one. The skill granted by the resulting base is completely random, which makes Absent Amulets with specific skill combinations highly valuable on the market. Profit Crafting Tips If you plan to craft for profit, you need to make sure that the free Spirit skill provided by Absent Amulet matches the + Skill Level modifier you are targeting. For example, Cast on Elemental Ailment can work with almost any + Skill Level modifier, but it should not be paired with + Minion Skills. Crafting Process Turn Absent Amulet Into a Rare First, make sure Absent Amulet has an Item Level of at least 75, as this is required for the +3 Skill Level modifier to appear. Start by using an Orb of Transmutation on it. Since Absent Amulet already has -1 prefix and -1 suffix, you cannot continue using an Orb of Augmentation to add another modifier. Instead, use a Regal Orb to turn it into a Rare and give it another modifier. Roll the Target Modifier With Chaos Orbs Once the amulet is Rare and has only one modifier, start using Chaos Orbs until you roll T1 Spirit or +3 Skill Level. If you roll a + Skill Level modifier that does not match what you want, you can simply sell the base, as it can still be valuable to other players. You can use Craft of Exile to calculate the expected crafting cost. Sometimes, simply getting a base with an existing +3 Melee Skills or +3 Spell Skills modifier for 20 Divine Orbs can actually be more economical. Add Another Modifier Once you have the target modifier, activate an Omen of Greater Exaltation and then use a Greater Exalted Orb on the amulet. If the amulet has Spirit, it is recommended to use a Divine Orb to roll Spirit to 50 first, because once the modifier is Fractured, it can no longer be modified or adjusted with a Divine Orb. You can use a Preserved Collarbone to Fracture Absent Amulet. The chance of Fracturing Spirit is approximately one-third. If it fails, most of PoE2 currency invested beforehand is essentially lost, and you will have to start over. Remove Modifiers After successfully Fracturing the modifier, use an Orb of Annulment to remove the other modifiers, leaving only one modifier. If you Fractured +3 Melee Skills, you can now add Quality and raise it to +4. If you Fractured Spirit, it is recommended to wait until you roll + Skill Level with Chaos Orbs before adding Quality. Otherwise, you may roll mismatched modifiers such as +3 Minion Skills or +3 Spell Skills, causing Quality investment to be wasted. Increase Quality Jewellery Quality is normally capped at 20%, but after using an Essence of the Breach, the maximum Quality can be increased to 40%. This step does not require an additional Omen because only the relevant modifier can be removed at this point. Quality can be added with Catalysts, which also come from Breach Genesis Tree. Fracture  Fracture Skill Level If you Fractured + Skill Level, the next step is to use Chaos Orbs until you roll T1 Spirit. Then activate an Omen of Dextral Exaltation and use a regular Exalted Orb. The suffix added at this stage does not matter. Next, activate an Omen of Dextral Crystallization and use a Perfect Essence of Enhancement. The Essence will only remove suffix and add Spirit, along with Global Armor, Evasion and Energy Shield. At this point, the crafting process is basically complete. All that remains is to repeatedly use Desecrate and an Omen of Light until you get the final modifiers you want. Fracture T1 Spirit If you have already Fractured T1 Spirit, skip the earlier Quality step and instead use Chaos Orbs to roll + Skill Level. Activate an Omen of Sinistral Exaltation and then use a regular Exalted Orb to add a random prefix. The specific modifier does not matter. Next, use an Omen of Sinistral Crystallization together with an Essence of the Breach. This will grant Quality, which you should then raise above 34% so that the +3 Skill modifier becomes +4. After that, you need to remove the maximum Quality. You can use an Omen of Whittling or an Omen of Sinistral Eraser. If you want to conserve some currency, activate an Omen of Sinistral Necromancy and then use a Preserved Collarbone. Since Spirit has already been Fractured, this will only remove the maximum Quality. You will then gain a Desecrate Prefix. This prefix is usually not ideal because what you actually want is All Skills Quality, which is a suffix. Therefore, activate an Omen of Sinistral Crystallization again and use a Perfect Essence of Enhancement. This removes Desecrate modifier while adding Global Armor, Evasion and Energy Shield. After that, continue using Desecrate and an Omen of Light to roll the desired modifiers. This process is indeed somewhat complicated, and you need to prepare various types of currency as well as an Absent Amulet base. However, as long as you follow these steps, you can obtain the modifiers you want. The exact amount of currency required will ultimately depend on RNG.
