Always on

• Eldritch Blast

  When Action

  A blast of crackling force lashes out at a foe, the signature spell of his pact and the simplest expression of his will.

• Hex

  When Bonus Action

  He marks a target with a curse that intensifies his harm and sharpens his pursuit of hidden weakness.

• Command

  When Action

  A glare, a whispered clause, and a target finds itself compelled by a single terrible command.

• Armor of Shadows

  When At will

  With fiendish restraint, he wraps himself in magical protection and moves through shadows with scholarly patience.

• Pact Magic and Eldritch InvocationsLevel 1

  You have made a pact with an extraplanar patron and draw on that bond for your magic and special abilities. As a 10th-level Warlock, your patron grants you class features at levels 1, 2, 3, 4, 6, 8, 9, and 10. Your spellcasting uses Charisma, and your Pact Magic gives you two 5th-level spell slots that refresh on a Short Rest.

• Eldritch InvocationsLevel 1

  You have discovered forbidden lessons that become Eldritch Invocations. At 10th level, you have seven invocations. Recommended choices for Edgar include Agonizing Blast, Armor of Shadows, Devil's Sight, Eldritch Mind, Mask of Many Faces, Repelling Blast, and Beguiling Influence.

• Magical CunningLevel 2

  You can perform an esoteric rite for 1 minute to regain expended Pact Magic spell slots, up to half your maximum, rounded up. Once you use this feature, you cannot use it again until you finish a Long Rest.

• Fiend PatronLevel 3

  You gain the Fiend patron. Your magic is tied to the Lower Planes, and your patron's evil aims are something you can use, resist, or exploit.

• Dark One's BlessingLevel 3

  When you reduce an enemy to 0 hit points, or when someone else reduces an enemy within 10 feet of you to 0 hit points, you gain temporary hit points equal to your Charisma modifier plus your Warlock level.

• Ability Score ImprovementLevel 4

  You gain the Ability Score Improvement feat or another feat of your choice for which you qualify. In this build, the requested final ability scores are already set by the character concept.

• Fiend SpellsLevel 3

  You know and prepare the Fiend spells granted by your patron at this level and lower. At 10th level, those spells are Burning Hands, Command, Scorching Ray, Suggestion, Fireball, Stinking Cloud, Fire Shield, Wall of Fire, Geas, and Insect Plague.

• Dark One's Own LuckLevel 6

  When you make an ability check or a saving throw, you can add 1d10 after seeing the roll but before the result takes effect. You can use this feature a number of times equal to your Charisma modifier, and you regain all uses on a Long Rest.

• Ability Score ImprovementLevel 8

  You gain another Ability Score Improvement feat or another feat of your choice for which you qualify. In this build, the requested final ability scores are already set by the character concept.

• Contact PatronLevel 9

  You can contact your patron directly. You always have Contact Other Plane prepared, you can cast it without expending a spell slot to contact your patron, and you automatically succeed on the spell's saving throw. Once you cast it this way, you cannot do so again until you finish a Long Rest.

• Fiendish ResilienceLevel 10

  Choose one damage type other than Force whenever you finish a Short or Long Rest. You have resistance to that damage type until you choose a different one with this feature. For Edgar, Necrotic is a fitting choice.

In practice, you can secure access to libraries, monasteries, and private collections through your reputation as a careful researcher.
