Lancelot is a special unit in Stronghold Legends and only available to those users who are currently playing as the Arthur faction. He is recruited from The Round Table, and costs 500 gold and 125 Honour. You can find out ways to generate Honour in the game here.
His general skills and abilities mirror that very much of a standard Knight. His attack strength is virtually identical to that of a Knight in standard combat as well- in straight out combat between Lancelot and a Knight, it's essentially the unit that strikes the first blow that will win.
By default, Lancelot will be mounted when you purchase him from The Round Table. You can dismount him from his horse by selecting him and then clicking on the "dismount" icon.
Once mounted on a horse, any enemy units must first kill the horse before they can attack Lancelot himself, so there are great advantages of doing so, besides Lancelot moving a lot faster. The horse alone takes 2 Crossbow bolts to kill.
If the Horse is killed or you dismount Lancelot, you can mount Lancelot on another horse, but must wait for a short "recharge" time before this button becomes available again. To do this, select Lancelot and then click on the "Mount horse" icon. Note that by mounting Lancelot, like any unit, it will cost 20 Honour. Once you have attempted to mount him, a horse will instantly appear and he will automatically be mounted.
You can only have one Lancelot unit at any time. If he is killed, you will instantly be able to purchase another Lancelot unit from The Round Table again. Like all ground units from The Round Table, Lancelot has a special power, in his case called The Sword of Albion. This special power will provide a large boost to troops within the radius of where this power is activated, almost doubling their attack strength for a time.
You can activate this special power by left-clicking on the sword icon on the right side of your screen, and right clicking on the map where to use it, benefitting all units within its range. It can only be used somewhere within Lancelot's range already, and once used, it will require a "recharge" time. During this, the green line around the outside of the sword icon on your screen must reach all the way around to the start before it can be used again.
This icon is only available while Lancelot is alive, so if Lancelot dies or you have not yet recruited him, you must recruit another Lancelot from The Round Table again in order to use it. Only he has the ability to use this power.
Once Lancelot's power has been used, his own attack strength and that of other units around him will increase dramatically. In straight out combat with a Knight, Lancelot will decimate the other Knight losing only half of his own health. Not only that but he can also kill a second Knight in a lone fight and still survive, all of these units being fully mounted.
However as Lancelot is so similar to a Knight, the same weaknesses also apply to him. Without use of his horse, he is a very slow moving unit. He can easily get overwhelmed by defence systems such as Burning Logs, Ballistae or pitch ditches. And he can also very easily be picked off by ranged or aerial units, frozen by Ice units and have his health sputtered away over time by persistent attacks or fire. This is primarily due to the fact he moves so slowly.
Lancelot will also struggle against units such as Frost Giants, even whilst mounted, simply because Frost Giants are so powerful and can cause an enormous amount of damage. It's therefore extremely important to protect him well to prevent this from happening, particularly if the enemy is playing as a different faction with access to more advanced units and magical powers, as most of these are not limited.
Tip: Lancelot's power is extremely powerful and can cause serious trouble for enemy units if used at the correct time. The best time for using this is when you're almost on top of the enemy during a siegeor have already breached their walls, and the enemy has no choice other than to fight your units.
Simply move in Lancelot, activate his power and nearby units will automatically attack with more strength, decimating enemy units. All this means that Lancelot's power works together very nicely with Bedivere's Horn of Camelot for maximum damage.
