Lance Royal Guards are the elite corps of soldiers within the Crimson Lance and are rarely encountered.
Another such appearance, where this time they must be fought, is in the company of Master McCloud. A pair of them are sent with him to eliminate the cornered Vault hunters sneaking into the Crimson Fastness. In the second DLC, Mad Moxxi's Underdome Riot, if Master McCloud spawns in the boss wave, two Lance Royal Guards will accompany him.
Lance Royal Guards have high health and wear heavy armour, comparable to that of Lance Defenders and/or Engineers, and is visibly differentiated by a purple colour scheme. This armour is often paired with a shield, which makes them very tough to kill. However, this armour also slows them down, making them easy to outmanoeuvre. They fight much like Lance Infantry, with automatic weapons, seeking cover when taking fire, and ducking down behind cover to reload their weapons. Unlike Infantry, Royal Guards will try to close in to get more accurate fire on their targets.
Corrosive, and Shock weapons are the recommended choice of armament to use against Lance Royal Guards because of their heavy armor, and shields. Fast firing SMGs, combat rifles, and shotguns are also effective at getting critical hits on their heads, causing them to flinch, and whittling down their high health.
