Blood Knight of Ardour

Blood Knights are dedicated to Ardour, King of Hell. While not necessarily evil, Ardourants tend to be more interested in meeting their own ends than in how a thing gets done. The Blood Knights gain power through sacrifice. You have learned to use your own blood to fuel your spells.

Bonded Weapon

You can use your action to create a bonded weapon in your empty hand. You can choose the form that this melee weapon takes each time you create it (see chapter 5 of the Player's Handbook for weapon options). This weapon counts as magical for the purpose of overcoming resistance and immunity to nonmagical attacks and damage.

Your bonded weapon disappears if it is more than 5 feet away from you for 1 minute or more. It also disappears if you use this feature again, if you dismiss the weapon (no action required), or if you die.

You can transform one magic weapon into your bond weapon by performing a special ritual while you hold the weapon. You perform the ritual over the course of 1 hour, which can be done during a short rest. You can then dismiss the weapon, shunting it into an extradimensional space, and it appears whenever you create your pact weapon thereafter. You can't affect an artifact or a sentient weapon in this way. The weapon ceases being your bonded weapon if you die, if you perform the 1 hour ritual on a different weapon, or if you use a 1 hour ritual to break your bond to it. The weapon appears at your feet if it is in the extradimensional space when the bond breaks.

Invocations

At 7th level, you may choose one eldritch invocation from the available options. You may choose a second at 15th level, and a third at 18th level. You must meet the invocation's prerequisite to learn it. You can change one of your Invocations each time you level up

You can now inscribe magical rituals in your Book of Shadows. Choose two 1st-level spells that have the ritual tag from any class’s spell list (the two needn’t be from the same list).

You can’t cast the spells except as rituals, unless you’ve learned them by some other means. You can also cast a spell you know as a ritual if it has the ritual tag.

On your adventures, you can add other ritual spells to your Book of Shadows. When you find such a spell, you can add it to the book if the spell’s level is equal to or less than half your fighter level (rounded up) and if you can spare the time to transcribe the spell. For each level of the spell, the transcription process takes 2 hours and costs 50 gp for the rare inks needed to inscribe it.
