BloodBlade

Through a lessor pact similar to a Warlocks pack the fighters blood has been cursed, However the curse allows the fighter to caste spells in a similar way as those trained to become Eldritch knights however instead of studies their magics come from their blood

Blood Magic

Cursed Blood flows through the Bloodblade granting great power however to caste spells at their greatest potential instead of their base level causes great strain of the Bloodblades life force hurting him/her in doing so.

Spells caste by a Blood blade cannot be up-caste unless you sacrifice Hit points equal to 1d4xspell level this sacrifice is a free action however can make a Bloodblade reduce to 0 hit points. (i.e to casting the lv1 spell Hellish Rebuke as a 3rd lv spell the Bloodblade must first declare he/she is sacrificing 3d4 hit points 11d4 for each lv including the spells original level)

If The sacrifice reduces the Bloodblade to 0 hit points the spell Automatically hits however the Bloddblade is then rendered unconscious immediately after resolving the spells effect

If a creature with blood dies as a result of one of your spells you heal 1d4x the spells level to a minimum of 1d4 hit points healed (the healing is improved to 1d8xspell level at level 10)

Spellcasting

When you reach 3rd level, you augment your martial prowess with the ability to cast spells. See Spells Rules for the general rules of spellcasting and the Spells Listing for the warlock spell list.

Cantrips

You learn two cantrips of your choice from the warlock spell list. You learn an additional warlock cantrip of your choice at 10th level.

Spell Slots

The Eldritch Knight Spellcasting table shows how many spell slots you have to cast your warlock spells of 1st level and higher. To cast one of these spells, you must expend a slot of the spell’s level or higher. You regain all expended spell slots when you finish a long rest.

For example, if you know the 1st-level spell shield and have a 1st-level and a 2nd-level spell slot available, you can cast shield using either slot.

Spells Known of 1st-Level and Higher

You know three 1st-level warlock spells of your choice, two of which you must choose from the abjuration and evocation spells on the warlock spell list.

The Spells Known column of the Eldritch Knight Spellcasting table shows when you learn more warlock spells of 1st level or higher. Each of these spells must be an abjuration or evocation spell of your choice, and must be of a level for which you have spell slots. For instance, when you reach 7th level in this class, you can learn one new spell of 1st or 2nd level.

The spells you learn at 8th, 14th, and 20th level can come from any school of magic.

Whenever you gain a level in this class, you can replace one of the warlock spells you know with another spell of your choice from the warlock spell list. The new spell must be of a level for which you have spell slots, and it must be an abjuration or evocation spell, unless you’re replacing the spell you gained at 3rd, 8th, 14th, or 20th level from any school of magic.

Spellcasting Ability

Constitution is your spellcasting ability for your warlock spells, since you learn your spells through your cured blood. You use your Constitution whenever a spell refers to your spellcasting ability. In addition, you use your Constitution 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 Constitution modifier

Spell attack modifier = your proficiency bonus + your Constitution  modifier
