Jsk School of Dark Arts

Dark Arts Savant
At 2nd level, your study of the dark arts has unearthed forgotten eldritch power, fragments of dark knowledge that offer you unusual methods of using your magic. You learn the Eldritch Blast cantrip and two Eldritch Invocations of your choice. You learn an additional two Eldritch Invocations at 7th, 12th, and 18th level.

If an Eldritch Invocation has a prerequisite, you can choose that Eldritch Invocation only if you meet the prerequisite. A level prerequisite refers to your Wizard level, instead of your Warlock level. An Eldritch Invocation that uses a Warlock spell slot uses a Wizard spell slot for you: the spell slot much match the spell level that the spell is being cast at.

Your dark powers are malleable and can be twisted to suit your needs. When you finish a long rest, you can choose one Eldritch Invocation that you know and replace it with another Eldritch Invocation that you could learn at that level.

Furthermore, when you gain a Wizard level and can add spells to your spellbook, you can choose to add Warlock spells instead of Wizard spells. When you find a Warlock spell of 1st-level or higher, you can add it to your spellbook if it is of a spell level you can prepare and if you can spare the time to decipher and copy it. For each level of the spell, the process takes 1 hour and costs 25gp. The cost represents material components you expend as you experiment with the spell to master it, as well as the fine inks you need to record it. Once you have spent this time and money, you can prepare the spell just like your other spells. When added to your spellbook, these spells count as Wizard spells for you.

Outer Influence
At 2nd level, your studies into the occult have opened your body, mind, and soul to the influence of powerful beings. You can choose a patron to be influenced by from the Warlock's Otherworldly Patron feature. When you do so, you gain the 1st Level features associated with that patron. If the patron has a spell list, those spells are considered Wizard spells for you, but are not automatically added to your spellbook.

Any feature that uses Warlock levels instead uses Wizard levels for you, and any feature that uses your Charisma uses your Intelligence instead.

Black Magic
At 6th level, you can transform your lesser magics into powerful features. When you finish a short or long rest, you can expend a 1st-level spell slot to choose one of the following abilities. You can only have one ability effecting you at a time, and choosing another one causes the first effect to end.

Unknown
You can hover up to 3 feet above the ground or a liquid that fills a 5-foot space. While hovering, you can use your speed to move as you normally would. When you fall from a height, you take no damage from the first 20 feet that you fall, unless you are unconscious or your speed is 0.

Dark Deflection
When you are hit by an Attack that you can see, you can use your Reaction to gain a +2 bonus to your AC against the Attack, potentially causing the Attack to miss. When you do this, you can only cast cantrips until the end of your next turn.

Overcast
When you cast a spell that deals damage, you can choose to overcast the spell. When you overcast the spell, you cast the spell at one spell level higher than the spell slot that you are expending to cast the spell. As you cast the spell, you roll a number of d4's equal to your Wizard level and take necrotic damage equal to the result. This damage cannot be reduced or avoided by any means, and you take the damage before you finish casting the spell. You cannot overcast a spell of 5th-level or higher.

Otherworldly Secrets
At 10th level, you have delved deeper into the mysteries surrounding the patron you study. You learn the 6th Level features of your Otherworldy Patron choice. Any feature that uses Warlock levels instead uses Wizard levels for you, and any feature that uses your Charisma uses your Intelligence instead.

Greater Otherworldly Secrets
At 14th level, you learn the 10th Level features of your Otherworldy Patron choice. Any feature that refers to a Warlock instead refers to a Wizard for you, and any feature that uses your Charisma uses your Intelligence instead.
