Frost Knight (5e Subclass)
From D&D Wiki
Frost Knight[edit]
Fighter Subclass
Frost knights are warriors who are trained in a special kind of magic, that grants them the ability to manipulate the primordial power of ice, a branch of water elemental control. They use this magic, alongside with their martial abilities to gain an edge on battles. Not all creatures that have such power become frost knights, and anyone who choose this path and survive long enough are considered the chosen champions of their communities, being respected and feared for the connection and control they have over the destructive force of ice.
It is more common for frost knights to be native from arctic environments, due to the proximity with the elements they intend to control and since this magic was created by arctic tribes who devote elements of winter, but this is not a strict rule, and the power of frost can be controlled on any sort of environment.
Some of these warriors inherit the natural power to control frost, having in their bloodline the blood of ice giants or white dragons. Other's, however, seek for this power, diligently training for years to master it while attuning their senses to this ice magic.
