Grow Empire: Rome: How to Beat Wave 100

To beat Wave 100 in Grow Empire: Rome, prioritize upgrading your Wall Archers and Wall HP, deploy Roman infantry to stall enemy clusters outside the gate, and reserve active area-of-effect skills for high-density pushes.

Upgrade Allocation Before Wave 100

Wave 100 features larger, denser enemy formations with increased health pools. Because wall repairs occur between waves rather than during combat, enter the wave with sufficient wall durability to absorb breakthrough hits while your ranged emplacements clear the field.

Invest your gold according to these priorities before launching the wave:

Upgrade Category	Priority Level	Tactical Role on Wave 100
Wall Archers	High	Primary continuous damage; eliminates raiders before they reach the gate
Wall Level (HP)	High	Structural buffer against siege units and charging cavalry
Roman Melee Troops	Moderate	Mobile frontline; pins attackers inside the archer kill zone
Rampart Towers	Moderate	Passive armor-piercing damage against heavy targets via Ballistas and Catapults
Auxiliary Heroes	Low to Moderate	Supplementary crowd control and burst damage during critical pushes

Level your Wall Archers until their base damage can defeat basic raiders in two to three hits. This prevents incoming waves from overcrowding the frontline. Supplement them with fixed wall emplacements, such as Ballistas and Catapults, which fire continuously even when your deployed field units fall.

Tactical Troop Deployment

Roman Spearmen and swordsmen are not meant to eliminate the attacking army on their own. Their primary objective is anchoring hostile units in the kill zone directly in front of the wall, allowing rampart defenses to deal maximum damage.

To manage the frontline during Wave 100:

Hold deployment at the start: Do not summon infantry against scattered initial scouts. Releasing units prematurely exposes them to incoming ranged fire without support.
Intercept shock charges: Deploy a squad of melee defenders as enemy shock troops or cavalry cross into the approach zone. Halting them outside the gate clumps hostile units together.
Stagger reinforcement cycles: Rotate troop summons as previous squads fall. Keeping deployment cooldowns cycling ensures fresh units maintain the defensive line until the assault ends.

Active Ability Timing

Avoid triggering siege abilities against lone advance units. Rotating your active skills against dense intersections maximizes damage and prevents the gate from being overwhelmed:

Boulder Strike: Activate this skill when enemy shock units collide with your deployed Roman infantry. The impact deals heavy area-of-effect damage and knocks surviving units backward, resetting their momentum.
Arrow Rain: Use this against backline archers and fast-moving raiders approaching mid-range. Activating it as reinforcements gather softens their health pools before they join the frontline engagement.

Alternate these two skills so at least one high-impact offensive option remains off cooldown when a new wave cluster approaches.

Next Action

Collect accrued tribute gold from your conquered colonies, apply remaining funds to your Wall Archers and Wall HP, and start Wave 100 with all active skill cooldowns ready.
