Demon King (5e Class)

Demon King

The Demon King, what once was a lowly imp rose above the devilish ranks in spite of all odds crawled out from the underworld with a new breath and new purpose, with innate magical prowess Demon Kings set off on their own to live a life they never could have had.

Demon King Lore

After I escaped my prison only a few came to look for me cornered and with an imp closing in I reach for my dagger and strike the imps torso, my blade shatters upon impact out of fear I try and strike with my fist to my surprise my fist opens revealing sharp claws with no time to think I sink my claws into the eyes of the fiendish imp with a howl and a screech it covers its eyes giving me a small time to escape I run and run until I can only crawl finding a small cave I rest, dreaming I find myself longing for power to not be tied down by fear anymore. Years have passed with decades of experience I enter into the nine hells once more but this time I feel home.

A Demon King is one who successfully escaped the underworld in pursuit for a new life but with demonic powers. Most return to the underworld and join the war on devils to be one of hells nine rulers using summoned fiends and contracts they have made with foolish mortals they believe they can make a once absurd dream reality.

Demonic Claws

What makes a Demon King demonic is his influence, the number of servants he has depends on the amount of strength in his claws strong enough to tear flesh to the bone.

At 1st level you have the signature weapon of being a demon- your claws. They deal necrotic damage equal to your current level on the table above. You are proficient with them and can make two claw attacks when you take the attack action on your turn.

Demonic Life

At 2nd level, your body undergoes a small change your heart beats slower and your skin looks younger, you stop aging but you can still be magically aged. You can also physically change your body to suit your needs. You also no longer need to eat, drink, breathe or sleep.

Spellcasting

By 2nd Level, you have learned to draw your hellish magic similar to the ways a warlock does but your powers come from you granted by your distance bloodline.

Preparing and Casting Spells

The Demon King table shows how many Spell Slots you have to cast your Spells. To cast one of your Demon King Spells of 1st level or higher, you must expend a slot of the spell's level or higher. You regain all expended Spell Slots when you finish a Short Rest.

You prepare the list of Demon King Spells that are available for you to cast, choosing from the Warlock and Sorcerer spell list. When you do so, choose a number of Spells equal to your Charisma modifier + half your Demon King level, rounded down (minimum of one spell). The Spells must be of a level for which you have Spell Slots.

For example, if you are a 5th-level Demon King, you have four 1st-level and two 2nd-level Spell Slots. With a Charisma of 14, your list of prepared Spells can include four Spells of 1st or 2nd Level, in any combination. If you prepare the 1st-level spell Unseen Servent, you can cast it using a 1st-level or a 2nd-level slot. Casting the spell doesn't remove it from your list of prepared Spells.

You can change your list of prepared Spells when you finish a Short Rest. Preparing a new list of Demon King Spells requires time spent in focusing your magic and harnessing it: at least 1 minute per Spell Level for each spell on your list.
