Rune Blade

Rune Blades enhance their martial prowess using the supernatural power of runes, an ancient practice that originated with giants. Rune cutters can be found among any family of giants, and you likely learned your methods first or second hand from such a mystical artisan. Whether you found the giant’s work carved into a hill or cave, learned of the runes from a sage, or met the giant in person, you studied the giant’s craft and learned how to apply magic runes to empower your equipment

 Runes Known

Whenever you finish a long rest, you can touch a number of objects equal to the number of runes you know, and you inscribe a different rune onto each of the objects. To be eligible, an object must be a weapon, a suit of armor, a shield, a piece of jewelry, or something else you can wear or hold in a hand. Your rune remains on an object until you finish a long rest, and an object can bear only one of your runes at a time.

The following runes are available to you when you learn a rune. If a rune has a level requirement, you must be at least that level in this class to learn the rune. If a rune requires a saving throw, your Rune Magic save DC equals 8 + your proficiency bonus + your Intelligence modifier.

Spellcasting

Also at 3rd level, you augment your combat techniques with the ability to cast spells. See chapter 10 of the Player’s Handbook for the general rules of spellcasting and chapter 11 of the Player’s Handbook for the Sorcerer spell list.

Cantrips. You learn three cantrips of your choice from the Sorcerer spell list. You learn an additional Sorcerer cantrip of your choice at 10th level.

Spell Slots. The Rune Blade Spellcasting table shows how many spell slots you have. The table also shows what the level of those slots is; all of your spell slots are the same level. To cast one of your Sorcerer spells of 1st level or higher, you must expend a spell slot. You regain all expended spell slots when you finish a short or long rest.

For example, when you are 8th level, you have two 2nd-level spell slots. To cast the 1st-level spell witch bolt, you must spend one of those slots, and you cast it as a 2nd-level spell.

Spells Known of 1st Level and Higher. At 3rd level, you know two 1st-level spells of your choice from the warlock spell list.

The Spells Known column of the Profane Soul Spellcasting table shows when you learn more warlock spells of your choice of 1st level and higher. A spell you choose must be of a level no higher than what’s shown in the table’s Slot Level column for your level. When you reach 13th level, for example, you learn a new warlock spell, which can be 1st, 2nd, or 3rd level.

Additionally, when you gain a level in this class, you can choose one of the warlock spells you know and replace it with another spell from the warlock spell list, which also must be of a level for which you have spell slots.

Spellcasting Ability. Intelligence is your spellcasting ability for your warlock spells, so you use your Intelligence whenever a spell refers to your spellcasting ability. In addition, you use your Intelligence modifier when setting the saving throw DC for a warlock spell you cast and when making an attack roll with one.

Spell save DC = 8 + your proficiency bonus + your Intelligence modifier

Spell attack modifier = your proficiency bonus + your Intelligence modifier

Primordial Blood

Starting at 3rd level, your weapon becomes a conduit for the power of your pact with your chosen patron. While you have an active crimson rite, you can use your weapon as a spellcasting focus for your warlock spells, and you gain the following benefits

• Any weapon you are holding gains the finesse property. 
• Once on each of your turns, one of your attacks with a weapon or an unarmed strike can deal an extra 1d6 damage to a target on a hit.

Mystic Frenzy

Starting at 7th level, when you use your action to cast a cantrip, you can immediately make one weapon attack as a bonus action.

Revealed Arcana

At 7th level, your Bloodline grants you the use of a distinctive spell. You cast this spell using any pact magic spell slot, and can’t do so again until you finish a long rest.

Brand of the Sapping Scar

Upon reaching 11th level, your Brand of Castigation feature digs dark arcane scars into your target, leaving them vulnerable to your magic. A creature branded by you has disadvantage on saving throws against your Sorcerer spells.

Unsealed Arcana

At 15th level, your Bloodline grants you the use of an additional spell. You cast this spell without expending a spell slot, and can’t do so again until you finish a long rest.

Blood Curse of the Souleater

Starting at 18th level, you learn to siphon the life energy from your fallen prey. You gain the Blood Curse of the Soul Eater for your Blood Maledict feature. This doesn’t count against your number of blood curses known.
