Another thing their cheap Castles can do is help them create their unique unit, the Throwing Axeman. This allows them to both build more Castles and build them earlier, making them better at securing parts of the map and pressuring the enemy directly. Another major advantage is their 25% cheaper Castles. They have a strong early- and mid-game economy, due to their faster gathering Foragers and free Farm upgrades, respectively. A smaller but still notable buff is the extra Line of Sight, something appreciated by a unit that normally has a low Line of Sight. Their unique technology, Chivalry, is not a trade-off, giving Stables a 40% work rate, allowing the Franks to replenish lost forces faster. While the Knight line is better off with this, their Light Cavalry and Cavalry Archers are not (though the latter are not a viable option regardless). Their mounted units receive +20% hit points, though this is partially offset by their lack of Bloodlines. 5.2 Disadvantages vs other civilizations.
