Build a defense that can recover

Firefly’s castle guidance consistently separates economy, walls, troops and extra defenses. Apply that pattern here: protect routes to the wall, overlap ranged fire, keep a breach reserve and test pitch ignition before a wave. Repair and resupply before changing several variables at once.

Practical strategy

Use Archer against lightly armored attackers; add Crossbowman when armor becomes the problem. Longbowman brings longer range at a slower firing rate. Mixed ranged units cover different threats; adding more of one type is not always the answer.
Put Tower Ballista on a compatible tower: Octagon Tower, Horseshoe Tower or Great Tower. Protect access and inspect the firing angle. Keep a close-range reserve behind the gate rather than assuming tower fire will stop every breach.
Combine Pitch Rig, Pitch Ditch, Brazier and an archer in range. The brazier belongs on a stone wall. Check the archer can ignite the ditch before battle, then time the fire for a dense enemy group; do not rely on an unattended trap.
Test one weak point at a time in free build. Repair a gap, replenish weapons and food, then summon the next wave. Captain supports nearby troops; a slow armored front line needs ranged cover. Fear-driven production has a military trade-off, so it is not a free combat bonus.
