Doom Knight

The Doom Knight is known for their use of heavy armor coupled with mastery of sword, spear, shield or any other martial weapon in use. Though this is not the only aspect the have access too, they also can dip into magic to supplement their combat skills making them an even more dangerous foe to face. Elite and few in number, Doom Knights seldom choose to fight for the sake of the fight, only when honor demands such a task be undertaken. Beware the Doom Knight should you face one, as their retribution is swift and exact.

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 wizard, Sorcerer, and Warlock spell lists.

Cantrips

You learn two cantrips of your choice from the wizard, Sorcerer, or Warlock spell list, with the exception of Eldritch Blast. You learn an additional cantrip of your choice at 5th, 10th, and 15th levels.

Spell Slots

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. You may also use a Ruinic Charge to cast any of these spells in place of the Spell Slot (only one Ruinic Charge may be spent per turn this way.)

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 wizard spells of your choice, two of which you must choose from the spells on the wizard, Sorcerer, or Warlock spell list.

The Spells Known column of the Doom Knight Spellcasting table shows when you learn more spells of 1st level or higher. Each of these spells 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 spells you know with another spell of your choice from the wizard, sorcerer, or warlock spell list. The new spell must be of a level for which you.

Spellcasting Ability

Charisma is your spellcasting ability for your spells, since you learn your spells through study and memorization. You use your Charisma whenever a spell refers to your spellcasting ability. In addition, you use your Charisma modifier when setting the saving throw DC for a wizard spell you cast and when making an attack roll with one.

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

Spell attack modifier = your proficiency bonus + your Charisma modifier

YOUR SPELLBOOK

The spells that you add to your spellbook as you gain levels reflect the arcane research you conduct on your own, as well as intellectual breakthroughs you have had about the nature of the multiverse. You might find other spells during your adventures. You could discover a spell recorded on a scroll in an evil wizard’s chest, for example, or in a dusty tome in an ancient library.

Copying a Spell into the Book. When you find a wizard 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.

Copying that spell into your spellbook involves reproducing the basic form of the spell, then deciphering the unique system of notation used by the wizard who wrote it. You must practice the spell until you understand the sounds or gestures required, then transcribe it into your spellbook using your own notation.

For each level of the spell, the process takes 2 hours and costs 50 gp. 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.

Replacing the Book. You can copy a spell from your own spellbook into another book—for example, if you want to make a backup copy of your spellbook. This is just like copying a new spell into your spellbook, but faster and easier, since you understand your own notation and already know how to cast the spell. You need spend only 1 hour and 10 gp for each level of the copied spell.

If you lose your spellbook, you can use the same procedure to transcribe the spells that you have prepared into a new spellbook. Filling out the remainder of your spellbook requires you to find new spells to do so, as normal. For this reason, many wizards keep backup spellbooks in a safe place.

The Book’s Appearance. Your spellbook is a unique compilation of spells, with its own decorative flourishes and margin notes. It might be a plain, functional leather volume that you received as a gift from your master, a finely bound gilt-edged tome you found in an ancient library, or even a loose collection of notes scrounged together after you lost your previous spellbook in a mishap.

Ruinic Casting

At 3rd level, you gain the ability to cast your known spells through the use of the Ruinic Charges. Once this level has been achieved you can begin gain these charges as well. The method for obtaining these charges is this:

-  If a spell through a use of Ruinic Charge connects and kills the targeted creature that Charge is refunded.

- Studying Ruinic Lore Texts and Tomes will also grant another Ruinic Charge.

At the 3rd level you gain access to 3 Ruinic Charges. At levels 7, 11, 16, 20 you gain an additional Ruinic Charge. You regain all expended Ruinic Charges during a Long Rest.

 

Ruin's Gift

Beginning at 7th level, you may cast any cantrip you know as a bonus action. You may also cast Cantrips through Ruinic Charges with this feature.

Ruin's Riposte

At 10th level, when you hit a creature with a weapon attack, it has disadvantage on the next saving throw it makes against the next cantrip or spell you cast  before the end of your next turn. When you hit the creature with a cantrip, it's Armor Class is reduced equal to your proficiency bonus until the end of your next turn.

Arcane Charge

At 15th level, you gain the ability to teleport up to 30 feet to an unoccupied space you can see when you use your Action Surge. You can teleport before or after the additional action.

Improved Ruin's Gift

Starting at 18th level, when you use your bonus action or expend a Ruinic Charge to cast a Cantrip, you gain an additional bonus action to cast a known spell of 5th level or lower.
