Loop Hero Necromancer Guide: The Infinite Scaling Strategy for Chapter 4

To become truly unstoppable in Loop Hero, you must pivot your strategy toward the Necromancer class and focus specifically on optimizing skeleton scaling. Unlike the Warrior or Rogue, the Necromancer does not rely on direct damage or evasion; instead, your success is tethered entirely to the efficiency of your undead army. By manipulating your deck to maximize Attack Speed and Skeleton Quality, you can bypass the traditional damage-dealing struggles of earlier classes. This approach relies on consistent gear farming and calculated tile placement to ensure your summons overwhelm enemies before they can land a hit, effectively turning late-game loops into a trivial experience.

Prioritizing Stats for the Necromancer

The Necromancer’s combat effectiveness is determined by three specific metrics: Attack Speed, Skeleton Level, and Skeleton Quality. Understanding the hierarchy of these stats is essential for survival in the later chapters of Loop Hero.

• Attack Speed: This is your most vital modifier. It dictates how quickly you can initiate the summon cycle. If your attack speed is too low, your front line will be decimated by powerful Chapter 4 enemies before you can summon replacements. High attack speed ensures that even if a skeleton falls, a new one is summoned almost instantly to maintain your defensive wall.
• Skeleton Level: This increases the base health and damage of your skeletons. As you progress through deeper loops, enemy HP scales rapidly; if your skeletons are under-leveled, they will be one-shot by late-game mobs.
• Skeleton Quality: This determines the chance for your Necromancer to summon a "better" version of a skeleton (e.g., a Guard or a Warrior skeleton with higher health and damage). Higher quality is the primary factor in defeating elite enemies.

When equipping gear, ignore flat damage or evasion bonuses. Focus exclusively on gear that stacks Attack Speed and Skeleton Level, with Quality acting as the secondary priority once your speed threshold is met.

The Power of the Arsenal Gold Card

To reach your peak potential, you must utilize the Arsenal gold card. This card grants you an additional equipment slot—the Shield—which is otherwise unavailable to the Necromancer.

The Shield is essential because it provides access to the Magic HP stat. Magic HP acts as a secondary buffer that absorbs damage before your primary health pool is touched. In Chapter 4, where enemy damage output scales aggressively, Magic HP is the difference between a successful loop and a premature retreat. While the Arsenal slightly dilutes the loot pool by adding more item types, the mathematical advantage of having a Magic HP buffer significantly outweighs the minor reduction in gear consistency.

Deck Construction: The River-Forest Synergy

Your deck construction should prioritize tiles that provide resources and stat-boosting environments without cluttering the map with dangerous enemies. The core of the infinite scaling build is the synergy between Forest and River tiles.

1. Placement: Place River tiles to double the effectiveness of adjacent Forest/Thicket tiles.
2. Scaling: Forests provide a flat bonus to your Attack Speed. By carefully pathing your River tiles, you can push your attack speed to levels that render your Necromancer nearly immune to incoming damage because the enemy is constantly staggered by your rapid-fire summons.
3. Density: Avoid placing too many high-threat monster tiles early in the loop. You want to reach a state where you have sufficient gear to handle the boss encounters without burning through your health potions. Focus on clearing "safe" tiles to farm high-level equipment before integrating more difficult enemy-spawning tiles like Vampires or Blood Groves.

Mastering the Combat Loop

The "secret" to this strategy is knowing when to stop the loop and manage your resources. Because the Necromancer scales so aggressively with gear, you should aim to complete as many loops as possible to accumulate resources, but be aware of the "soft cap" on enemy strength.

If your skeletons start dying in single hits, it is a sign that your Skeleton Level is falling behind the map’s scaling. At this point, it is time to retreat. Loop Hero rewards consistency; losing a run because you pushed for one more loop when your summons were failing is the most common mistake made by players. Prioritize replacing your current gear with items that boost quality if you find your skeletons dying too quickly, even if it means sacrificing a small amount of Attack Speed. Maintaining the balance between summon frequency and individual skeleton durability is the hallmark of an advanced Loop Hero player.

Long-Term Progression and Base Upgrades

Your deck strategy is useless without the underlying infrastructure provided by your base. Ensure you are consistently using the resources gathered during your runs to upgrade the Field Kitchen, Herbalist’s Hut, and Smithy.

• Smithy: Focus on upgrading this early. It directly impacts your ability to find higher-tier gear in the field. Better equipment drops mean your Necromancer requires less luck to find the perfect stat combinations (e.g., high speed + high level).
• Herbalist’s Hut: Essential for potion capacity. As you push deeper, you will inevitably take chip damage; having more potions allows you to survive the intense difficulty spikes encountered in Chapter 4.
• Field Kitchen: Provides a vital healing bonus for every loop completed, which helps offset the minor damage you take while your skeletons are being summoned.

By continuously refining your base alongside your in-run strategy, you create a feedback loop of power. This infrastructure allows you to clear Chapter 4 with minimal effort, effectively becoming an unstoppable force in the infinite loop. Remember: the game is a marathon, not a sprint. Focus on your gear stats, utilize the Arsenal for that critical Magic HP buffer, and keep your Attack Speed high to keep your skeleton army—and your run—alive.
