Kingdom of Camelot Wall Defenses Guide for Caltrops
* The purpose of Caltrops is to slow the attackers at maximum range while the army and other defenses attack them at range.
* Caltrops do very little damage; they rarely kill troops alone.
* Caltrops are completely ignored by Cavalry, Supply Wagons, and Siege Engines: they move right past.
* Caltrops should be used with Archers and other range troops defending your city, or with wall-mounted crossbows.
* Caltrops are the cheapest and most efficient field defense unit for might-building.
Spiked Barriers
* Spiked Barriers stop both types of Cavalry, Siege Engines, and Supply Wagons until they are destroyed.
* Spiked Barriers do some damage and can easily wipe out Supply Wagons if they are ignored.
* Spiked Barriers are completely ignored by infantry troops: they move right past.
* Like Caltrops, Spiked Barriers work best when holding enemy attackers at range for your other troops and defenses.
Traps
* Traps are single-use defenses - they will be destroyed when they attack enemy troops.
* Traps do a lot of damage, nearly guaranteeing that the attackers will take some losses.
* Traps are very ineffecient against smart or high-level attackers. Traps are not worth the cost of the units they destroy, and a smart attacker will send in militia to trigger your traps.
Wall-Mounted Crossbows
* Crossbows are very effective defensive units and have a longer range and can do much more damage than Archers.
* Crossbows work very well with Caltrops and Spiked Barriers to hold the enemy at their long range.
* Crossbows have shorter range than Ballista and Catapults, so they are susceptible to attacks from these units.
* Crossbows are the most cost- and space-effective wall defense unit for might-building.
Kingdom of Camelot Wall Defenses Guide for Defensive Trebuchets
* Trebuchets will only attack Siege Engines and will completely ignore all other units, including supply wagons.
* Trebuchets have an enormous range and very high damage, virtually guaranteeing that it will destroy an enemy siege engine before it can get into range.
* Trebuchets are single-use defenses: they will be destroyed when they fire upon an enemy Siege Engine.
