Grow Empire: Rome: How to Defend Colony 101 at Level 165

To defend Colony 101 at level 165 in Grow Empire: Rome, hold the engagement line away from your gate by staggering melee troop deployments, timing wall abilities to hit dense clusters, and neutralizing incoming siege engines before they reach your barricade.

Wall Ability Timing and Priority Targets

Passive archer fire chips down individual units, but level 165 enemy waves will overrun your wall if active abilities are wasted on early scouts. Save high-impact skills until enemy ranks compress against your deployed infantry.

Ability	Optimal Timing	Primary Target
Boulder Throw	Fire when heavy infantry packs collide with your front line	Dense melee clusters
Arrow Rain	Launch when enemy ranged units halt to fire	Archers and skirmishers
Ballista Volley	Fire down lanes containing rams or armored commanders	Armored siege units and leaders

Firing abilities at the point of frontline impact removes shock troops instantly, allowing wall archers to redirect their fire to trailing units.

Frontline Deployment Rotation

Deploying all infantry units at once leads to simultaneous squad wipes from enemy area damage, leaving your gate exposed while spawn timers recharge. Stagger your spawns to keep a permanent buffer in the field:

Deploy the lead squad: Send spearmen or legionaries forward once the enemy vanguard crosses the battlefield midpoint, locking attackers within range of your wall archers.
Deploy the second wave at half strength: Call in your next melee unit when the active squad drops to roughly 50 percent health so fresh troops arrive before the line breaks.
Intercept cavalry charges: Direct durable infantry into incoming cavalry to absorb charge momentum before they bypass your perimeter.
Deploy reserves against siege engines: Release a held squad immediately if battering rams or heavily armored shock troops punch through the skirmish line.

Hero Buffs and Disruption

Hold hero skills for peak enemy pressure rather than activating them immediately:

Damage buffs and shouts: Trigger offensive boosts when enemy champions or elite shock troops engage your line, allowing your infantry to clear the mob quickly.
Stuns and knockbacks: Save crowd-control abilities for moments when enemy reinforcement waves threaten to overwhelm your defenders, buying time for squad spawn bars to refill.

Preparation and Upgrade Benchmarks

Before launching the defense of Colony 101 at level 165, ensure your garrison meets these core upgrade thresholds:

Wall Archers: Upgrade damage until foot soldiers drop within two to three focused volleys.
Melee Infantry: Raise health and armor so spearmen and legionaries survive sustained cleave damage.
Wall Health: Maintain sufficient durability to absorb stray projectile fire and incidental siege hits during wave transitions.
Cooldown Reduction: Invest in general cooldown skills to ensure Boulder Throw and Ballista Volley cycle multiple times during the assault.
