Wanderers, are you in search of Obtoite? This guide will show you an efficient and incredibly fun farming loop to stockpile enough Obtoite, fill your supplies, and complete your masterworking for the season. It involves utilizing Nightmare Dungeons, including Escalating Nightmare Dungeons, along with some tips for efficient Sigil powder farming and strong room mechanics. If you’re looking to speed up your progress, you can also buy Diablo 4 Gold to help boost your resources. Let’s dive in!

Diablo 4 Season 12: The Ultimate Obtoite Farming Guide

Step 1: Entering the Nightmare Dungeon

To kick off your farming journey, you’ll need to complete Nightmare Dungeons. The key here is finding Herodrick Strong Rooms, which can significantly boost your rewards. As soon as you enter a Nightmare Dungeon, you’ll notice a purple beam guiding you to the Herodrick Strong Room. Once you’ve found it, activate it and prepare to face several waves of enemies. These waves will open a portal that lets you enter the Herodrick Strong Room itself, where you’ll face more waves of monsters. After these waves are cleared, you’ll face five different choices. These choices will affect the speed and rewards of your farming loop.


Step 2: Choosing the Right Buffs

The key to speeding up your Obtoite farming is making the right choice from the five available options. You’ll encounter Legendary Choices that provide buffs. Some notable ones are:

· Summon Special Demon Buff: This one is crucial. If you spot it, choose it immediately, as it increases your reward bar significantly after defeating the demon.

· Pillar Ritual Buff: Look for the Pillars that give you 25% increased ritual speed. This is an excellent choice for increasing your Herodrick Strong Room reputation and rewards.

· Evade Buffs: If you’re constantly moving and avoiding damage, consider taking buffs that increase your Herodrick Attunement when carrying certain idols.

· These buffs will make your journey through the Strong Rooms faster and more rewarding. Remember, not all choices will be equally effective, so make sure to read through them quickly before making your decision.


Step 3: Activating Pillars and Completing Rituals

Next, you’ll need to activate Pillars inside the dungeon. Each pillar will trigger a new event where you’ll kill monsters to complete rituals. These rituals will increase your Herodrick Attunement. Once your ritual is complete, a new event will spawn. Move quickly from pillar to pillar, clearing enemies as you go, and keep an eye on the minimap to ensure you’re always on the right path. At the end of the ritual, a boss will spawn. Killing this boss rewards you with Escalating Nightmare Dungeon Keys and Obtoite (roughly 800 per run, assuming you complete the reputation board).


Step 4: Escalating Nightmare Dungeons

After gathering your Escalating Nightmare Dungeon Key, you’ll dive deeper into the Escalating Nightmare Dungeons. These dungeons will consist of three consecutive dungeons with progressively harder enemies and affixes. Completing each dungeon unlocks the next, eventually leading you to the final boss: Asteroth. As you clear each dungeon, focus on completing them quickly, as your goal is to keep the loop moving. Each time you finish a dungeon, a new portal will appear to guide you into the next. Some dungeon affixes might be harder than others, so make sure you’re well-prepared before entering.


Step 5: The Strong Room Farming Loop

The key to continuing your Obtoite farming cycle is ensuring you’re consistently farming Strong Rooms. These rooms will provide the escalating Nightmare Dungeon keys you need to move forward in the farming loop. Once you’ve completed the Escalating Nightmare Dungeon, you’ll need to look for another Strong Room. These rooms drop additional Escalating Nightmare Dungeon keys, allowing you to continue the cycle. This is where you’ll get Obtoite in bulk, as long as you’re continuously completing these rooms.


Step 6: Managing Your Sigil Powder

In case you run low on Sigil Powder, there are a few methods for efficiently farming it. The best place to gather it is from Hell Tides, where you’ll find:

· Tree of Whispers Caches

· Elite Monsters

· Tortured Gifts

· You can also find Sigil Powder by completing Hell Tide events, as well as farming Elite Monsters in these zones. Once you’ve accumulated enough Sigil Powder, you can craft Nightmare Sigils, which are essential for continuing the loop.


Step 7: Preparing for the Boss: Asteroth

Eventually, you’ll reach Asteroth, the final boss in the Escalating Nightmare Dungeon. Asteroth is tough and tanky, so make sure your character is highly survivable and capable of handling the damage output. While your farming build may lack raw DPS, it’s important to have enough damage over time (DoT) effects like Earthquakes to ensure you can defeat Asteroth. Upon defeating Asteroth, you’ll receive more Nightmare Dungeon Keys and additional loot, including valuable boss materials. This loot will help you further improve your character and progress toward getting the perfect gear for the season.


The Never-Ending Obtoite Farming Cycle

This farming loop is one of the most efficient methods for gathering Obtoite in Diablo 4 this season. By continuously completing Escalating Nightmare Dungeons, collecting Strong Room keys, and managing your Sigil Powder, you’ll be able to masterwork your gear and stay ahead in the game. If you want to speed up your progress, you can also buy Diablo 4 Items from trusted sources like MMOEXP to give you the boost you need in your farming endeavors. The key to success here is maintaining strong movement speed and high survivability, especially when taking on the Escalating Nightmare Dungeons. Once you’ve established this loop, you’ll have a steady flow of Obtoite, gear upgrades, and dungeon keys to fuel your farming endeavors. Happy farming!
