Tainted knights who follow a dark path of blood and slaughter.
Fallen Knights are very similar to Dark Slayers in Vez'nan's army: slow, sluggish but very powerful in combat, able to quickly cleave through soldiers with ease. However, unlike the heavily armored Dark Slayers, Fallen Knights have no armor but instead are virtually impenetrable to magical attacks with their 90% resistance, making high-leveled archers and artillery essential to stop them. Even death cannot stop them, as when Fallen Knights are killed, they'll immediately return as Spectral Knights, with the ability to boost their living comrades and complete immunity to physical damage; only when the Spectral Knight is slain is the Fallen Knight dead for good. The Spectral Knights' physical immunity and the Fallen Knights' high magic resistance make a very powerful and annoying combo when they spawn together.
- Teslas deal very high damage to them.
- Rangers are also useful, especially with Wrath of the Forest, which traps them and deals good damage.
- Fallen Knights have a fast attack speed in addition to their high damage so they can kill low-level soldiers and unarmored heroes with ease.
- Arcane's Death Ray will quickly get rid of Fallen Knights. They will not turn into Spectral Knights when this happens.
- Physical instant kills such as the Musketeer Garrison's Sniper Shot and Hacksaw's Tiiimber will turn Fallen Knights into Spectral Knights.
- Fallen Knights that are killed by the Fat Boy in Shop will turn them into Spectral Knights.
