How to Use Ground Flat HP Refines to Protect Mounted Troops in Evony

In Evony: The King’s Return, the difference between a successful defense and a catastrophic loss often comes down to the subtle mechanics of damage calculation. For high-level players, one of the most persistent issues is the vulnerability of mounted troops when facing heavy siege-based attacks. Experimental data indicates that by strategically utilizing Ground Flat HP refines on your gear, you can create a "damage buffer" that significantly reduces mounted troop casualties.

This guide details the mechanics of this defensive strategy, how Flat HP refines interact with the game’s combat engine, and how you can optimize your gear to preserve your most valuable offensive units during intense PvP engagements.

The Mechanics: Why Ground Flat HP Matters

To understand why Ground Flat HP refines are effective, you must first understand how Evony calculates troop priority and damage absorption. In a defensive engagement, your troops are organized into a formation that dictates the order in which they take damage. Ground troops typically serve as the frontline screen.

When an enemy siege attack hits, it must calculate damage against your frontline units before it can effectively reach the backline where your high-damage mounted troops reside. By stacking Flat HP, you are increasing the "effective health pool" of your frontline. This is not about percentage-based scaling; it is about providing a static, high-value floor that forces the enemy’s siege damage to focus on your ground units for a longer duration. When your ground units hold their position, they absorb a greater portion of the incoming "alpha strike," leaving your mounted troops significantly safer.

The Correlation Between Frontline Stability and Mounted Survival

High mounted casualties often occur because the enemy’s siege damage "leaks" through the frontline too quickly. If your ground units are wiped out in the first few rounds of combat, your mounted troops become the primary target for the enemy’s remaining siege fire.

By applying Flat HP refines, you achieve three critical defensive outcomes:

• Increased Damage Soak: The higher HP total forces the enemy combat engine to allocate more hits to the ground units to achieve a "kill."
• Reduced Mounted Exposure: Every extra round your ground units survive is a round where your mounted troops are effectively shielded from the primary barrage.
• Optimized Trade Ratios: Because mounted troops are expensive and difficult to replace, keeping them alive even at the cost of ground losses is almost always a favorable trade for your long-term server viability.

Strategic Gear Selection for Refines

Not all gear is created equal when it comes to applying these refines. To maximize the impact, you should prioritize pieces that allow for the highest concentration of HP-based bonuses.

1. Prioritize High-Tier Gear: Focus your best refining stones on Achaemenidae or Ares gear, which provides the largest base stat pools.
2. Targeted Slots: Identify gear pieces that offer "Flat HP" as a potential refine stat. Aim for gold-tier refines, as the difference between a purple and gold Flat HP refine is substantial when multiplied across multiple pieces of equipment.
3. The "Sweet Spot" Iteration: Do not blindly apply refines to all gear. Use a two-step approach: apply Flat HP to two pieces, conduct a mock battle or analyze a report from a recent server-versus-server (SvS) event, and check your wounded breakdown. If you see a decrease in mounted wounded, continue; if the impact is negligible, consider re-evaluating your debuff layers.

Balancing Trade-offs: When Flat HP Isn't Enough

While Ground Flat HP is a powerful defensive tool, it is not a replacement for comprehensive combat stats. Players must be careful not to sacrifice too much Attack or Defense percentage in the pursuit of HP.

• The Diminishing Returns Problem: There is a threshold where additional HP provides less utility than an increase in damage reduction or attack speed. If your ground units are already sufficiently durable, shifting focus back to your general’s specialties might yield better results.
• General Synergy: These refines are most effective when paired with generals who have HP-boosting specialties or skills. A high-HP general paired with Flat HP-refined gear creates a synergy that is significantly harder to break than gear alone.
• Enemy Composition Awareness: If you are being attacked by pure ranged units, the benefit of Ground Flat HP is diminished, as ranged units often bypass the ground frontline or target differently than siege engines. Always scout your opponent to ensure this strategy aligns with their offensive composition.

Integrating Defense with Subordinate City Debuffs

In Evony, individual gear refines function best when they are part of a larger, systemic defensive strategy. Your gear is only one layer of the onion.

To ensure your Flat HP strategy works, you must continue to focus on your subordinate cities. The most effective way to protect your troops is to reduce the opponent's stats before they even hit your walls. Ensure your subordinate cities are equipped with the appropriate debuffing generals (such as those providing "Enemy Troop Attack" or "Enemy Troop Defense" reductions). When you combine strong debuffs with a high-HP ground frontline, you force the attacker to fight against a significantly weakened and highly resilient wall, which is the gold standard for defensive play in Evony.

Practical Steps to Implement Your Strategy

To begin optimizing your defense today, follow this systematic approach:

1. Audit Your Current Reports: Review your most recent battle reports. Identify the exact ratio of ground to mounted wounded. If the mounted wounded count is disproportionately high, your frontline is failing too quickly.
2. Select Your Gear: Choose 2–3 pieces of gear dedicated to Ground HP.
3. Refine for Gold: Use refining stones to roll for gold-tier Flat HP. Avoid settling for lower-tier stats, as the multiplicative nature of the game’s combat formulas makes high-tier stats significantly more impactful.
4. Test and Adjust: Participate in a controlled test or analyze the next SvS engagement. If the mounted wounded count drops, you have successfully stabilized your frontline. If you still see high losses, re-check your subordinate city debuffs to ensure they are active and leveled correctly.

By mastering these refinements, you move away from reactive, "luck-based" defense and toward a methodical, calculated approach that preserves your power and keeps your empire standing against even the strongest siege-heavy adversaries. In Evony, the player who controls the damage distribution wins the war of attrition.
