Stop Grinding at Low Levels! How to Unlock Purple Mythic War Plans & Farm the Hidden Horadric Gem in Diablo 4 Lord of Hatred?

Category: Diablo 4 Posted: May 18, 2026 Views: 63

Players, you've been playing Diablo 4 Lord of Hatred for a few weeks now, and you should be familiar with War Plans system, a brand-new endgame feature introduced in Lord of Hatred. Next, we'll discuss how to use War Plans to farm the various Diablo 4 rewards you need.

Upgrade all War Plans to level 10

There are multiple activities you can choose to complete within War Plans. Each completed round of a plan increases War Plan level of that activity, up to a maximum of level 10.

Once an activity's War Plan reaches level 10, even if you no longer actively schedule it, you will automatically receive all the max-level passive bonuses while playing that activity normally, completely transforming your gameplay experience.

More importantly, Mythic War Plans will only have a chance to spawn after all activities have reached level 10. These quests directly reward top-tier Diablo 4 items that cannot be obtained through normal means.

To obtain Mythic War Plans, you should upgrade all activities to level 10. Besides obtaining Mythic Unique items, if you encounter a Mythic War Plan, completing it will directly reward you with a Horadric Gem, which requires 5 Grand Gems to craft. This reward is arguably the most luxurious in the game.

Stop Grinding at Low Levels! How to Unlock Purple Mythic War Plans & Farm the Hidden Horadric Gem in Diablo 4 Lord of Hatred?

How to efficiently farm Mythic War Plans?

Once all your War Plans are maxed out, the core objective is to repeatedly refresh the plan table to find Mythic War Plans, especially those that reward gems.

Each time you complete a War Plan round, you can reroll three times for free. If no Mythic War Plan appears, prioritize the shortest activity combination, such as Nightmare Dungeon, The Undercity, or Lair Bosses, completing them quickly to advance to the next round.

Helltide takes a long time. Unless you have absolutely no other options, prioritize resetting plans that include Helltide.

Different colored rewards on the table correspond to different qualities, but for Mythic War Plans, don't get bogged down in regular rewards. Instead, keep resetting until a purple Mythic War Plan appears.

Core War Plans

Tree of Whispers

For Tree of Whispers, prioritize maxing out the left skill tree to obtain Corrupted Roots. Planting these in Nightmare Dungeon or Helltide has a high probability of summoning Headrotten Feast. Killing it triggers a large number of monsters and additional rewards, making it one of the strongest farming strategies this season.

The core node in the middle is Wisdom of Whispers. It provides extra experience, greatly aiding leveling.

The right node is more friendly to casual players, offering a chance to directly obtain Resplendent Sparks. It's recommended to prioritize investing in this when lacking Mythic gear.

Nightmare Dungeon

Players must select Gauntlet. When you activate Shrine, killing monsters stores souls. When Shrine ends, all souls will be released at once, which is equivalent to doubling the number of kills. Combined with Corrupted Roots from Tree of Whispers, this can generate massive monster hordes.

Fearless Conviction grants Attuned Primordial Dust in Nightmare Dungeon, a highly valuable material used this season to reroll Unique gear affixes.

Helltide

Players should prioritize Bursting Brood, which spawns numerous Maggots in Helltide, providing a massive amount of experience upon defeat, making it the best way to quickly level up Paragon.

Second priority is Meat Brothers, which spawns two Butchers. Killing them drops Profane Mindcage, which increases the monster level in Helltide. Higher monster levels significantly increase the quality and quantity of loot.

This War Plan requires almost no changes and is considered the optimal solution.

The Undercity

Gutter Filth is an absolutely core node in the The Undercity skill tree. It increases your final caches to 3-4, allowing you to obtain 4 Mythic items at once, making it the fastest way for newcomers to acquire Mythic gear.

Here's a pitfall players should avoid: don't select the node that adds extra cache but requires a key to open. The cache contains no special items, making it a complete waste of the node.

Lair Bosses

Lair of Runes and Lair of Plenty are two of the strongest damage-boosting nodes, directly granting the boss's Monster Power +1. This significantly improves drop quality and the drop rate of Mythic gear, making it core to any boss farming.

Selecting Ultimate Nemesis gives a chance to open a portal upon defeating a boss. Entering this portal leads to encounters with additional bosses, potentially triggering deeper portals. Players can obtain multiple Mythic items and a large amount of materials in a single encounter.

The last two nodes are completely customizable. Adjust them flexibly based on your current main farming content. For example, switch to Helltide-related nodes for Helltide farming, and to The Pit nodes for The Pit farming.

The Pit

If you're still upgrading your Glyph, prioritize selecting Choron's Blessing to increase Glyph Upgrade Chance by +1. Next, select Pit Buthcer to increase the chance of encountering Butcher. Defeating Butcher immediately ends the current Pit and grants all upgrade opportunities, significantly saving time.

To speed up completion, you can also select Heart of Stone, Choron's Haste, which allows you to complete Pits faster and gain more Glyph upgrade attempts.

Once all your Glyphs are maxed out, you can exchange excess Choron's Souls for equipment or experience points, but the experience gain is extremely low and not highly recommended.

Infernal Hordes

Most players may not enjoy this mode, but to upgrade all War Plans to level 10 and unlock Mythic War Plans, you still need to grit your teeth and level up.

The only efficient leveling technique is to find three other players who also want to level up, form a four-person team, and start Infernal Hordes in turn. After each round, take turns joining other players' rooms; this way, completing it once will increase the progress of multiple people simultaneously.

So, these are the farming strategies for various events in War Plans. Good luck farming for Mythic War Plans!
