Blessed Knight 2

The difference between a knight and a blessed knight was very important and meaningful and it came in the fact that while yes, all knights were respectively the chosen and best warriors of the various religions and most importantly could actively and passively draw on the power of the gods they served to train more effectively and unleash greater power when in battle, the number of them who could perform a descent was limited.

A descent was the ability of a knight to invoke what was believed to be an angelic or divine possession on his person. 

With this ability, one entered a state where they temporarily gained the powers of a mighty being unleashing devastation far removed from the capability of their own power and in some rare cases their order.
