Evony March Size Guide: How March Size Buffs Impact Combat

March size in Evony dictates the total number of troops you can launch in a single attack or rally. Expanding your march size directly increases the base volume of your army, supplying additional raw attack, defense, and HP on the battlefield. To maximize your combat effectiveness, prioritize expanding permanent march capacity through research and general development while using trial attacks to test temporary buffs against percentage stat boosts.

How March Size Affects Combat Mechanics

While percentage-based stat modifiers enhance the existing attributes of your units, march size increases the total count of active units. Adding new units raises the overall damage potential of your march beyond what minor percentage stat boosts achieve on a capped troop count.

Stat Expansion: Extra troops contribute their own base stats to the battle, increasing cumulative power output per round.
Target Distribution: A larger volume of troops provides more targets for enemy forces to absorb, preventing defensive layers from easily stalling your attack.
Rally Scaling: In alliance rallies or attacks on fortified keeps, higher march capacity helps penetrate deeper into multi-layered enemy defenses.

Comparing March Capacity to Percentage Buffs

Directly comparing march size buffs to percentage stat buffs depends on your troop composition and current power level. Percentage buffs can hit diminishing returns if troop capacity remains low, but march size scaling stays consistent as long as high-tier units fill the extra slots.

Metric	March Size Buffs	Percentage Stat Buffs
Primary Effect	Increases total troop volume	Raises base stats of existing units
Best Use Case	Deploying top-tier units (T13/T14)	Enhancing specific unit attributes
Limitations	Higher potential healing costs	Subject to diminishing returns

March size is most effective when deploying high-tier units like T13 or T14. Expanding march size with low-tier units primarily adds extra casualties without producing a proportionate spike in offensive output.

Operational Costs and Constraints

Increasing your march size creates specific trade-offs that require resource planning:

Hospital Bills: Deploying more troops leads to higher wounded counts during difficult engagements, increasing resource and speedup costs for healing.
Buff Volatility: Relying heavily on temporary items or short-term march bonuses creates temporary power spikes. If a temporary buff expires mid-conflict, your effective combat capacity drops significantly. Maintain a solid permanent baseline through keep progression and research.

Recommended Steps for Optimizing March Size

Follow these steps to integrate march size adjustments into your general strategy:

Audit Troop Tiers: Ensure your march capacity expands using your highest-tier available units rather than low-tier filler.
Apply Enemy Debuffs: Pair expanded march capacity with general debuffs targeting enemy attack and defense stats to prevent unnecessary troop losses.
Run Test Attacks: Attack smaller controlled targets while toggling temporary march buffs on and off, then check battle reports to measure damage scaling against percentage stat buffs.
Invest in Permanent Upgrades: Prioritize technology research and general gear that provide permanent march size additions over temporary consumable items.
