Ritualist

Experienced with the powers that be, Ritualist Rogues do not fear magic in its most raw, unfiltered form. Not as magically skilled as Arcane Tricksters, these Rogues generally rely on rituals. They practice some of the same traditions as the witches around them, and often are of Changeling heritage or training. While usually proud to stand in support of more traditional warriors, Ritualists are sometimes rumored to be sent by powerful political players to perform secret missions that blur the line between martial and magical skill.

All rogues have an appreciation for darkness – all the better to work in. You have a far more synergistic relationship with the shadows. They fuel your power, enhance your skills, and grant you the ability to perform spectacular feats. Maybe you made a minor pact with a shadow entity, have the blood of a creature of darkness in your veins, or are just lucky. Who can say? The results, however, speak for themselves.

3rd:

Arcane Training: You gain proficiency in the Arcana skill, and with the Athame. (If you already have proficiency in the Arcana skill, you gain a bonus proficiency of your choosing)

Pactbound Sneak Attack: When you deal sneak attack damage, you may choose to have half your sneak attack damage dealt as Necrotic or Force damage. Additionally, when you deal Sneak Attack damage while wielding an Athame, you add your proficiency modifier to the total damage dealt. (After the dice have been rolled, not per dice)

Ritualist: You gain the Book of Ancient Secrets warlock invocation, even if you do not qualify for it. You use your Rogue levels in place of your Warlock levels to determine the spells you can scribe into your ritual book.

9th:

Darkvision: You gain Darkvision out to 60 feet. If you already have darkvision, increase it's distance by 30 feet.

Improved Arcane Training: You gain Expertise in Arcana. (If you already have expertise in the Arcana skill, you gain a bonus expertise of your choosing) You may use scrolls and activate spell-trigger items as if you were a Warlock. The maximum level of Warlock spell you can activate for this purpose is equal to your proficiency bonus.

13th:

Hexed, Vexed, Perplexed: When you deal Sneak Attack damage to a creature, you may force the target to make an Intelligence saving throw. If they fail, they become confused, as per the spell Confusion, for 1 minute. The DC for this ability is 8+Proficiency Modifier+Dexterity Modifier. A creature affected by this ability gains a new saving throw at the end of it's turn to end the effect early. Once a creature has been successfully confused by this ability, they are immune to it until you successfully complete a long rest.

17th:

Kelias' Shadow: You gain the following features at 17th level:
-When wielding an Athame, you critically hit on a 19 or 20
-When you deal Sneak Attack damage with an Athame, you roll an additional 2d6 damage
-When you score a critical hit and deal sneak attack damage, you become Invisible, as per the spell. You may use this ability a number of times per day equal to your Dexterity modifier.
