- Alias: Ancient Cobalt Knight, Royal Cobalt Knight, Cobalt Knight
The Ancient Cobalt Knight. It is notably known as one of the five Ancient Knights that can be found in the Frontier. As its name implies, it shares resemblances to that of a knight in cobalt armor equipped with a cobalt greatsword.
There are three attacks that the Ancient Cobalt Knight can perform:
- Slash - Slashes the player with its greatsword.
- Slice - Wields its greatsword with both arms at both ends in an attempt to slice the player in half.
- Sweep - Sweeps the ground in front of itself.
- It is the 2nd weakest Ancient Knight, the first one being the Ancient Iron Knight.
- It is possible to acquire its weapon it wields and the collectible known as the Ring of the Five Knights, a ring equipment.
- It is one of the few Ancient Knights that players do not find very often, the other knight being the Ancient Onyx Knight.
