The Elder Dreadnaught

Your patron is a titanic creature of legend, forgotten for ages. Native from the astral plane, its power resides within its aptitude to find small rifts in the Weave and exploit it. If it has existed and still exists, the Elder Dreadnaught might be unaware of your existence or entirely indifferent to you, but the secrets you have learned allow you to draw your magic from its influence.

 

Expended spell list

The Elder Dreadnaught lets you choose from an expanded list of spells when you learn a warlock spell. The following spells are added to the warlock spell list for you.

1st — chaos bolt, detect Magic

2nd — magic weapon, Nystul’s magic aura

3rd — nondetection, protection from energy

4th — Mordenkainen’s sanctum, Otiluke’s resilient sphere

5th — dispel evil and good, Rary’s telepathic bond

Arcane Disrupter

Starting at 1st level, you gain the ability to disrupt a spell caster. You can use your bonus action and choose one creature you can see within 30 feet of you. For the next minute, the target has disadvantage on its Concentration check.

Once you use this feature, you can’t use it again until you finish a short or long rest.

Magic Sensibility

At 1st level, you gain the ability to detect the magical energy within 10 feet of you. When you sense magic in this way, you can use your action to see a faint aura around any visible creature or object in the area that bears magic, and you learn its school of magic, if any. You also know how long this magical aura has been in effect.

Your detection can penetrate most barriers, but is blocked by 1 foot of stone, 1 inch of common metal, a thin sheet of lead, or 3 feet of wood or dirt.

Once you use this feature, you can’t use it again until you finish a long rest.

Weave Reversal

Starting at 6th level, you can invert the raw effect of a spell. When a spell caster other then you make a spell attack or cast a healing spell, you can use your reaction to invert the effect of that spell on the target. You must be able to see the target of the spell you wish to reverse. The spell must be level 1 or higher and be of a level for which you have spell slots. Instead of taking damage, the target of that spell is healed by half of the damage inflcted by the spell (round down) or take full damage instead of being healed. For exemple, a target hit by a ray of sickness, would be healed by 1d8 hit points instead of taking 2d8 poison damage. If the target of the spell would be healed by cure woulds, it takes full damage instead of regaining hit points.

The target of the spell you reverse can be you. The reversal can only affect one target, if the spell affects multiple targets, you must choose one of the targets. If the spell has a second effect on the target, it applies normally.

Once you use this feature, you can’t use it again until you finish a long rest.

Chaotic Ward

Beginning at 10th level, your patron teaches you how to turn the magic of your enemies against them. You gain the ability to ward yourself with the chaotic essence of the weave. When you succeed on a saving throw against a mind-affecting spell or magical effect, you are immune to that spell for the next hour.

      Additionally, if you succeed on a saving throw against a damaging spell or magical effect, you can use your reaction to dispel its magic and create the effect of an hellish rebuke spell. You don’t use a spell slot or component for that spell. Roll a d8 to determines the type of damage of the hellish rebuke spell, as shown below.

1 — Acid

2 — Cold

3 — Fire

4 — Force

5 — Lightning

6 — Poison

7 — Psychic

8 — Thunder

Once you use this feature, you can’t use it again until you finish a short or long rest.

Eyes of the Astral

Starting at level 14th, you can use an action to open your eyes widely and creates a bright lighted area of antimagic, as in the antimagic field spell, in a 30-foot cone. The effect lasts for a number or round equal to your charisma modifier. Your speed is half while the cone is active. At the start of each of your turn you decides which way the cone faces. You can’t use this feature while your eyes are closed or while you are blinded.

Once you use this feature, you can’t use it again until you finish a long rest.
