You've been noticed by or sought the power of an otherworldly entity. Either given by the entity or stolen from them, you now possess their mark, giving you a portion of their power. Occult agents use this supernatural power in conjunction with their skills as a rogue to perform otherwise impossible tasks and traverse through planes unknown.

Mark of the Occult

When you choose this roguish archetype at 3rd level, choose an otherworldly patron available to warlocks. The physical manifestation of that otherworldly entity's power appears somewhere on your body in the form of a brand, giving you some of their power over the arcane.

Spell Slots. The Mark of the Occult table shows how many spell slots you have as well as what level those spell slots are. To cast one of your spells of 1st-level or higher, you must expend a spell slot. You regain all expended spell slots when you finish a short or long rest.

Spells Known of 1st-Level and Higher. You know two 1st-level spells of your choice, chosen from the warlock spell list expanded by the otherworldly patron you chose when you chose this archetype.

The Spells Known column of the Mark of the Occult table shows when you learn more warlock spells of 1st-level or higher. For instance, when you reach 6th level in this class, you can learn one new spell of 1st-level.

Whenever you gain a level in this class, you can replace one of the warlock spells you know with another warlock spell of your choice. The new spell must be of a level for which you have spell slots.

Spellcasting Ability. Charisma is your spellcasting ability for your warlock spells, so 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 warlock spell you cast and when making an attack roll with one.
