War Plans in Diablo 4: A Complete Guide to Pathing, Rewards, and Skill Trees

Every Diablo 4 player diving into Season 13’s endgame faces the same question: How do you build the most efficient War Plan to maximize rewards, minimize wasted time, and hit your goals fast?

War Plans completely reshape how you farm the endgame, turning scattered activities into a customizable, reward-focused journey. The best plan isn’t just about picking activities—it’s about matching your goals (gear, materials, XP, or rare drops) to the right path, prioritizing high-impact rewards, and choosing skill tree upgrades that amplify every run. Let’s break down how War Plans work, how to build your ideal path, and which activities deserve your focus.

Quick Answer (Best Activities by Priority)

If you just want the key takeaways:

• S-Tier Activities (Top Priority) → Helltides and Kurast Undercity, offering the best combination of speed, rewards, and flexibility for War Plans.
• A-Tier Activities (High Priority) → Nightmare Dungeons and Lair Bosses, ideal for targeted farming and quick, high-reward runs.
• B-Tier Activity (Medium Priority) → The Pit, great for glyph XP but limited in broader value this season.
• D-Tier Activity (Skip Unless Target Farming) → Infernal Hordes, slow and low-reward compared to other options.
• Passive Activity → Tree of Whispers, earned automatically, no pathing required.

Most players will mix these activities based on their goals—but prioritizing speed and high-tier rewards is the golden rule for any War Plan.

War Plans Basics: How the System Works

At their core, War Plans are two-part systems designed to tailor your endgame grind to your goals:

• Left Panel: Activity Paths → A branching set of activities you choose to chain together, with each selection leading to different rewards at the end of your plan. Once locked in, your path can’t be changed, so choosing wisely is critical.
• Right Panel: Activity Skill Trees → Seven unique skill trees (one for each activity) that modify rewards, add bonuses, or introduce new challenges. These upgrades directly impact the quality and quantity of loot you’ll earn from every run.

Every activity in War Plans also supports its own skill tree paths, so even if you pick the same activity as another player, your upgrades can lead to wildly different rewards.

How to Build an Optimal War Plan

When you start a War Plan, you’ll face a series of branching choices. Each activity connects to the next, and once you commit to a path, there’s no going back. The key to success is simple: prioritize activities that give the highest-tier rewards in the shortest possible time.

Not all rewards are created equal. Here’s how to rank them by importance for your pathing decisions:

1. Dungeon Keys → The most critical resource for endgame boss farming.
2. Salvaging Materials & Horadric Reagents → Essential for crafting and upgrading gear.
3. Gold and Obols → Core currencies for rerolling, gambling, and purchases.
4. Experience Orbs → Key for leveling and glyph progression.
5. Obducite → Used for advanced crafting and upgrades.
6. Armor/Weapons/Spoils → Less reliable, but still valuable for targeted farming.

Each of these rewards comes in six tiers of quantity: Small, Medium, Large, Giant, Grand, and Mythic. Your goal? Route for the highest-tier versions of the most important rewards, while picking activities you can complete quickly with strong base rewards.

Activity Breakdown: Tier Rankings & Optimal Skill Tree Paths

Helltides (S-Tier | Top Priority)

Helltides are the undisputed king of War Plan activities—and for good reason.

Helltides are the top-tier War Plan activity: they deliver Lair Keys, Forgotten Souls, and massive XP all at once – unmatched multi-purpose value even with longer run times.

Skill Tree Breakdown

• Left Path: Boosts rewards and introduces Profane Mindcages (similar to Season 7’s mechanics), which increase monster level in exchange for more cinders, XP, and drops. Great for players looking to maximize raw gains.
• Middle Path (Recommended): The most impactful upgrade path for Helltides. Hellwyrm ambushes will spawn Maggots (dropping huge XP and boss trophies for Horadric Cube unique conversions) and a Pang of Duriel (dropping Lair Keys). This is the best way to farm Lair Keys, XP, and trophies in the game. Skip the other middle-path upgrades—they don’t compare.
• Right Path: Flexible utility options: avoid losing cinders on death (safer runs), gain 10 cinders every 100 collected (faster cinder farming), or unlock a 666-cinder Hells Prize chest for bonus loot. Pick based on your playstyle.

Kurast Undercity (S-Tier | Top Priority)

The Undercity is a War Plan staple, combining speed with highly customizable rewards.

Why they’re S-Tier: Blazing fast runs make them perfect for War Plan chaining, and the Tribute system lets you target exactly the rewards you need. All three skill tree paths are viable, so choose based on your goals.

Skill Tree Breakdown

• Left Path (Recommended): Focuses on end-of-run rewards, with better goblin loot drops and more Forgotten Souls per completion. Ideal for players prioritizing crafting materials.
• Middle Path (Recommended): The standout upgrade is the final node, which unlocks Ancestral Armament tributes. These can drop powerful unique and ancestral gear, making this path a top choice for loot-focused players.
• Right Path: Delivers massive XP gains and extra tributes per run. Perfect if you’re leveling or looking to maximize tribute options.

Nightmare Dungeons (A-Tier | High Priority)

Nightmare Dungeons are the most versatile War Plan activity, with consistent value and huge potential.

Why they’re A-Tier: Easy to complete for any build, with reliable base rewards. The right skill tree path unlocks some of the season’s rarest loot.

Skill Tree Breakdown

• Left Path: Boosts overall loot drops during runs, great for players just looking to pad their inventory.
• Middle Path: The only way to unlock the Astaroth loot table. The Recurring Nightmare node lets Escalating Nightmare Sigils drop after runs, which are key for accessing the hardest endgame content.
• Right Path (Recommended): All about Treasure Goblins, with rare chances at Mythic Uniques. If you’re chasing the season’s most coveted drops, this is the path to pick.

Lair Bosses (A-Tier | High Priority)

Lair Bosses are the fastest activity in War Plans, making them a no-brainer for quick, high-reward runs.

Why they’re A-Tier: Most runs take just seconds to complete. If the rewards align with your goals, they’re extremely easy to justify pathing into.

Skill Tree Breakdown

• Mixed Pathing (Recommended for Mid-Tier Players): Dip into the first nodes of the left and right paths to spawn Lair Bosses during other activities. This is especially useful if you’re targeting a specific boss’s loot table. The standout node here is Dog of Astaroth, which lets Nightmare Dungeon bosses drop from the Astaroth loot table—critical for farming the hardest-to-get Astaroth uniques.
• Middle Path (Recommended for Endgame Players): A chain of boss upgrades that rewards massive Hoard Chests from every Lair Boss. This is the most lucrative option, but only if you’re fully geared to handle the challenges.

The Pit (B-Tier | Medium Priority)

The Pit has been heavily nerfed this season, limiting its value to one key use case.

Why they’re B-Tier: While Glyph XP is still great, and lower-difficulty runs can be fast, the Pit’s only real purpose this season is leveling glyphs. It lacks the multi-purpose rewards of higher-tier activities.

Skill Tree Breakdown

Mixed Pathing (Recommended): Maximize glyph upgrades with Chrono’s Blessing (extra glyph upgrade chance) and the left-side Damned Thieves (boosts glyph progression speed). This is the only setup that makes the Pit worth including in your War Plan.

Infernal Hordes (D-Tier | Skip Unless Target Farming)

Hordes are the least efficient activity in War Plans this season.

Why they’re D-Tier: Extremely long run times with minimal relevant rewards. You could complete an entire War Plan in the time it takes to finish a 10-wave Horde. Only include them if you’re specifically farming for the Bertuc unique drop.

Skill Tree Breakdown

• Left Path (Recommended): The only viable option, offering better end-of-run rewards including more Bertuc uniques, talisman drops, and a choice between Obducite, Gem Fragments, or a Greater Hoard of Collection.
• Middle/Right Paths: Focus on Ather gains, but the rewards don’t justify the time investment compared to other activities. Skip these unless you’re desperate for Ather.

Tree of Whispers (Passive Activity)

The Tree of Whispers can’t be selected as a War Plan activity—instead, rewards are earned passively as you complete other objectives.

Skill Tree Breakdown

• Left Path: Introduces Corrupted Roots in Whisper Caches. Plant them to spawn enemies that drop extra loot and additional reward caches.
• Middle Path (Recommended): The two branches both lead to a final node with a chance for Whisper Caches to grant a Spark. Choose the left branch for bonus choices and better loot, or the right for more materials. Either works as long as you reach the Spark upgrade.
• Right Path: Adds ambushes after Whisper completions that drop Collection of Chaos rewards. The final node lets Varshan spawn in these ambushes, dropping Ancestral Cache of Chaos with top-tier loot.

Class synergy tip: AoE clear builds (e.g., Sorcerer, Rogue) excel at Helltides and Kurast Undercity – pick Middle Path Helltides + Left/Middle Undercity. Single-target burst builds (e.g., Barbarian, Necromancer) are faster at Lair Bosses and Nightmare Dungeons – go Middle Path Lair Bosses + Right Path Nightmare Dungeons.

Final Thoughts

The best War Plan isn’t a one-size-fits-all setup—it’s the one that matches what you want to achieve.

• Farming Materials/Crafting: Prioritize Helltides and Kurast Undercity for Forgotten Souls, keys, and reagents.
• Chasing Rare Uniques: Focus on Nightmare Dungeons (right path) and Lair Boss mixed pathing.
• Leveling/Glyph XP: Pick Kurast Undercity (right path) and The Pit (glyph-focused path).
• Casual Play: Mix Kurast Undercity and Nightmare Dungeons for balanced, low-stress rewards.

By prioritizing speed, high-tier rewards, and activities aligned with your goals, you’ll turn every War Plan into a step toward your endgame targets—no wasted time, no unnecessary grind.
