Evony K39 Defense Guide: How to Layer Troop Tiers

To defend a K39 city in Evony, place disposable lower- and mid-tier troops alongside your high-tier units to force incoming marches to distribute damage across multiple targets. Single-type or "flat" troop compositions allow enemy rallies to strike your strongest units directly. Creating structured layers buffers the strike, giving your wall general and defensive stat refines time to process combat rounds effectively.

How Troop Layering Works in Defensive Combat

combat mechanics resolve attacks against specific troop tiers and types based on march composition. If a city defense relies exclusively on high-tier units (such as T14 or T15), enemy rallies inflict immediate damage directly onto your primary offensive assets.

Layering introduces small, deliberate groups of lower-tier troops across ground, mounted, and ranged categories. Enemy damage resolves against these lower-cost layers first, stalling damage output and delaying direct damage to your high-tier anchor units.

Recommended K39 Layer Ratios and Tiers

A K39 defense relies on three distinct operational tiers across all three primary troop categories (ground, mounted, and ranged):

Layer Role	Troop Tiers	Target Quantities	Primary Function
Meat Shield	T1	High base volume	Absorbs initial rally damage at low resource cost
Mid-Tier Bridges	T5 and T10	50,000 to 100,000 each	Prevents enemy targeting from skipping straight to top tiers
Core Defensive Anchor	T14 and T15	Main force size	Delivers primary damage while protected by lower layers

Maintaining balanced layers across ground, mounted, and ranged categories prevents attackers from exploiting a single un-layered vulnerability. If an opponent identifies an un-layered ground force, a mounted-heavy rally can bypass your defenses entirely.

Wall General and Equipment Setup

Troop layers require active support from your wall general to remain effective:

Assign In-City Generals: Deploy a wall general whose skills specifically provide in-city percentage buffs to troop health (HP) and defense.
Match Refines to Composition: Align equipment refines with your primary layer structure. For example, if you maintain heavy ground layers, prioritize ground HP and ground defense refines on your wall general's gear.
Survive Combat Rounds: Layers keep your wall general alive longer in combat. If your wall general falls early in an engagement, all active defense buffs disappear, causing remaining layers to clear rapidly regardless of stack size.

Hospital Capacity and Layer Maintenance

Because lower and mid-tier layers are designed to take damage, they suffer casualties faster than your core troops.

Monitor Hospital Limits: Oversized layers can overflow hospital capacity during a full alliance rally, causing permanent troop loss. Keep total layer numbers within your maximum hospital allowance.
Replenish Layers Post-Combat: Check layer counts after every defense. An un-replenished layer creates a gap in your targeting bridge, exposing your T14 and T15 core units to full enemy damage on the next attack.
