Profane Soul

Blood hunters belonging to the Order of the Profane Soul have pushed the limits of hemocraft for use against some of the most terrifying creatures corrupting the world. Ancient fiends and cruel magic-users have long counted on their ability to meld into the background and escape those who hunt them, vanishing into noble courts without a trace, or bending the minds of the most stalwart warriors with but a glance. So the blood hunters who founded this order trusted to their resilience as they delved into the same well of corrupting arcane knowledge, making pacts with lesser evils to better combat the greater threats. And though they might have traded a part of themselves for their power, the members of this order know the benefits of that power far outweigh the price.
Pact Magic

3rd-level Order of the Profane Soul feature
The bargain you have struck with your Patron has granted you the ability to cast spells, much like a Warlock does:
Cantrips.
You learn two Cantrips of your choice from the Witch Knight spell list. Upon reaching 13th level in this class you learn one additional Profane Soul Cantrip of your choice.
Spell Slots.
The Profane Soul Spellcasting table shows how many spell slots you have, and the level of those spell slots. All of your spell slots from this feature are the same level. To cast one of your Profane Soul spells of 1st-level or higher, you must expend a spell slot. You regain all of your expended spell slots when you finish a short or long rest.
Spells Known of 1st-Level and Higher.
You learn two 1st-level spells of your choice from the Profane Soul spell list. The Spells Known column of the Profane Soul Spellcasting table shows when you learn more Profane Soul spells of 1st-level or higher. Spells you choose must be of a level no higher than the level in the table's Slot Level column for your level.
Whenever you gain a Blood Hunter level, you can choose one Profane Soul spell you know and replace it with another Profane Soul spell of a level for which you have spell slots.
Spellcasting Ability.
Intelligence is your spellcasting ability for your Profane Soul spells. You use your Intelligence when a spell refers to your spellcasting ability, when setting the saving throw DC, and when making a spell attack roll.
Spell save DC = 8 + your proficiency bonus + your Intelligence modifier
Spell attack modifier = your proficiency bonus + your Intelligence modifier

Crimson Smite

3rd-level Order of the Profane Soul feature
Magic seeps into the blood you sacrifice to empower your weapons. You can use any weapon empowered by Crimson Offering as a spellcasting focus for Profane Soul spells.
In addition, when you hit with a Crimson Offering attack, you can expend a Pact Magic spell slot to deal bonus damage of your Crimson Offering damage type. This bonus damage is two rolls of your Rite Die for a 1st-level spell slot, plus one roll of your Rite Die for each spell level higher than 1st.
Sanguine Warrior

7th-level Order of the Profane Soul feature
You seamlessly weave minor spells with weapon attacks. If you use your action to cast a Profane Soul spell, or activate a spell you are concentrating on (such as witch bolt), you can make a weapon attack as a bonus action on that turn.
Moreover, when you cast a Profane Soul spell while you are holding a weapon empowered by Crimson Offering, you can cause the spell to deal the damage type of your Crimson Offering in place of the normal damage of that spell.
Bewitched Strikes
13th-level Order of the Profane Soul feature
The Eldritch magic in your blood seeps into your weapons. When you hit a creature with a weapon attack, that creature has disadvantage on the next saving throw it makes against a Blood Rite or spell you cast before the end of your next turn.
Profane Sacrifice
18th-level Order of the Profane Soul feature
You can offer the death of your foes to your Eldritch Power for enhanced magicks. If a hostile creature dies within 30 feet of you, you can use your reaction to regain one Pact Magic spell slot, or gain temporary hit points equal to one roll of your Rite Die + your Intelligence modifier.
Once you use this feature you must finish a short or long rest before you can use it again.
