Expanded Spell List

The Seeker 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.

Spellcasting Ability

When you make a pact with the seeker patron, Intelligence is your spellcasting ability for your warlock spells, so you use your Intelligence whenever a spell refers to your spellcasting ability. In addition, you use your Intelligence modifier when setting the saving throw DC for a warlock spell you cast and when making an attack roll with one.

Shielding Aurora

Starting at 1st level, you can invoke the Seeker’s power to protect you from harm. As a bonus action, you create a whirling aurora of brilliant energy that swirls around you. Until the end of your next turn, you gain resistance to all damage, and if a hostile creature ends its turn within 10 feet of you, it takes radiant damage equal to your warlock level + your Charisma modifier.

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

Astral Refuge

At 6th level, you gain the ability to step into an astral refuge. As an action, you disappear from the world for a brief moment and enter the Astral Plane, taking advantage of its timeless nature.

While in your astral refuge, you can take two actions to cast spells that target only you without expending any of your warlock spell slots. After using those two actions, you return to the space you occupied and your turn ends.

Far Wanderer

At 10th level, you no longer need to breathe, and you gain resistance to fire damage and cold damage.

Astral Sequestration

Starting at 14th level, you gain the ability to sequester yourself and your allies on the Astral Plane.

By performing a special ritual over the course of 5 minutes, you shift yourself and up to ten willing creatures you can see to the Astral Plane. You and those creatures gain the benefits of a short rest while sequestered on the Astral Plane. You then return to the spaces you all occupied when you used this ability, with no time having passed in the world.

During this short rest, you and the creatures you sequester can make use of any options available during a rest that affect only you and the creatures you sequester.

Once you use this ability, you cannot use it again until you complete a long rest.

Pact of the Star Chain

At 3rd level, a character can select this option instead of one of the warlock’s existing Pact Boon options. The Seeker grants you a chain forged from starlight, decorated with seven gleaming motes of brightness. While the chain is on your person, you know the guidance cantrip and you know the augury spell and can cast it as a ritual. The spell doesn’t count against your number of spells known. You can use the star chain as a spellcasting focus for any of your warlock spells.

Additionally, you can invoke the Seeker’s power to gain advantage on an Intelligence check while you carry this item. You can use this ability a number of times equal to your Intelligence modifier per long rest.

If you lose your Star Chain, you can perform a 1- hour ceremony to receive a replacement from the Seeker. The ceremony can be performed during a short or long rest, and it destroys the previous chain. The chain disappears in a flash of light when you die.

The exact form of this item might be different depending on your patron. The Star Chain is inspired by the Greyhawk deity Celestian.

Path of the Seeker

Prerequisite: The Seeker patron

The Seeker bids you to travel in search of knowledge, and little can prevent you from waling this path. You ignore difficult terrain, have advantage on all checks to escape a grapple, manacles, or rope bindings, and advantage on saving throws against being paralyzed.

Seeker’s Speech

Prerequisite: The Seeker patron

Your quest for knowledge allows you to master any spoken language. When you complete a long rest, you can pick two languages. You gain the ability to speak, read, and write the chosen languages until you finish your next long rest.

Celestian's Ire

Prerequisite: Pact of the Star Chain

You can make a melee spell attack with your Star Chain as an action. The attack deals 1d8 radiant damage + your Intelligence modifier. This damage increases to 2d8 at 5th level, 3d8 at 11th level, and 4d8 at 17th level.

Starblast

Prerequisite: eldritch blast cantrip

When you cast eldritch blast, you deal additional radiant damage equal to your Intelligence modifier on a hit.

Visions of the Unseen Eye

Prerequisite: Pact of the Star Chain

Wielding your Star Chain reveals hidden truths in your environment. When you close your eyes, you can focus on your surroundings as an action, granting you blindsight to a distance of 60 feet for up to a minute as long as your eyes are closed. When you use this ability, one of the seven motes of brightness of your Star Chain dims. When all of the motes of brightness are dimmed in this way, you can no longer use this ability until you finish a long rest.

Cosmic Seer

Prerequisite: Pact of the Star Chain

When you finish a long rest, roll a d20 and record the number rolled. You can replace any attack roll, saving throw, or ability check made by you or a creature that you can see with this foretelling roll. You must choose to do so before the roll, and you can replace a roll in this way only once per turn. Each foretelling roll can be used only once. When you finish a long rest, you lose any unused foretelling rolls.

and identify. I figured these two spells would be both more useful and more flavorful for a seeker warlock. 2nd level spell levitate replaced with see invisibility. Passwall replaced with scrying because I just like scrying better.
