The knight, or, as abbreviated in the game, KNI, appears in the Castle's entrance and the Castle's keep. It has 70 hit points and uses a sharp sword as its weapon. They appear in large swarms, and may appear multiple times in each of these levels, essentially making it the main enemy of each level.
The knight is a bit tougher than its cousin, the guard.

The knight drops a knight body armor that gives you a 30% defense. It can be enchanted to shield you from 80% damage but halves your attack power.
