Grow Empire: Rome: How to Beat Elephant Armies in Invasions

To beat heavy elephant armies on the Invasions map in Grow Empire: Rome after completing level 165, immediately replace standard swordsmen swarms with dedicated spearmen, upgrade fort wall defense to absorb breach damage, and save hero stuns exclusively to interrupt elephant charges.

Countering Post-Level 165 Invasion Stat Scaling

Completing level 165 marks a significant difficulty spike where enemy stats on the Invasions map outpace regular Roman infantry cohorts. In regular campaign waves, basic swordsmen can absorb incoming damage. However, invasion nodes featuring War Elephants counter light frontline units through high health pools, broad cleave attacks, and massive structural siege multipliers.

When an elephant reaches standard foot soldiers, its cleave damage wipes out the squad in seconds. Once your frontline collapses, the elephant directs its siege attacks straight at your gate. Surviving these waves requires switching from general melee units to anti-cavalry counters and structural reinforcements.

Troop Selection and Tactical Priorities

Spearmen and pikemen possess innate damage bonuses and bracing capabilities against mounted units and heavy beasts. While swordsmen deal negligible chip damage against armored elephant defense values, spearmen apply piercing damage and slow down forward momentum outside the gate.

Deploy spearmen continuously to maintain a physical buffer outside the gate. Even when an elephant squad eventually breaks through, the delayed advance gives backline defenses time to wear down the target.

Fort Wall Durability Upgrades

Because high-level invasion beasts frequently push through ground forces, the fort wall must serve as a secondary defensive buffer rather than an untouchable structure. An under-leveled fort can lose half its integrity from just two or three unimpeded siege hits from an elephant.

Prioritize campaign gold into Fort Wall Health and Wall Defense before sinking excess capital into general infantry upgrades. A reinforced wall absorbs heavy breakthrough strikes without collapsing, creating an extended damage window for your wall artillery and hero cooldowns to finish the target.

Hero Skill and Stun Timing

Do not expend hero abilities on introductory infantry fodder. Invasion waves often deploy light screening units ahead of the war elephants, and wasting active skills early leaves your gate vulnerable when the primary threat arrives.

Execute this crowd control sequence when the wave approaches:

1. Hold skills during the initial rush: Allow frontline spearmen and tower archers to clear out light escorts without triggering hero cooldowns.
2. Interrupt the impact: Trigger a hero stun or knockback ability the exact moment the lead elephant engages your spearmen formation.
3. Apply damage buffs: Activate attack-speed buffs, morale boosts, or direct damage spells while the target is immobilized.
4. Stagger secondary heroes: If fielding multiple active commanders, wait for the initial stun duration to expire before launching the next crowd control skill to avoid overlapping timers.

Backline Artillery Roles

Upgrading backline ballistas and catapults provides the burst damage required to cut down high-tier elephant armor:

• Fort Ballistas: Focus on high single-target piercing damage that ignores a significant portion of elephant armor scaling.
• Catapults: Launch heavy area-of-effect boulders to clear the ground troops swarming around the elephant's flanks, preventing your spearmen from being overwhelmed by multiple angles.
