Path of the Death Knight

One a warrior for peace, order, and faith. Corrupted by the forces they sought to destroy. Now free, Will the death knight return to his teachings as a paladin? Or will they continue on their path of dark calling? 

Bound Weapon

A paladin who has taken the path of a Death knight gains the ability to create a living bond between themselves and their weapons. They perform a ritual over the course of 4 hours. The weapon must be within reach throughout the ritual, at the conclusion a bond is forged. Once you have bonded a weapon to yourself, you can't be disarmed of that weapon unless you are incapacitated in which the bond is broken.

You can summon that weapon as a bonus action on your turn, causing it to instantly materialize in your hand. In addition, as a bonus action, you may also absorb its physical form within your very being, which may act as an effective storage place. You can have up to two bonded weapons but can summon only one per bonus action. If you attempt to bond with a third weapon, you must break the bond with one of the other two.
