Pactbound

The pactbound rogue gains eldritch powers and spell sin return for their servitude to the power they serve.

Eldritch Channeling

At 17th level you have learnt to channel your spells into your sneak attacks. As a bonus action you ready a spell you can cast or have already active. Then the next time you do sneak attack damage, before the end of your next turn, the spell goes off as well. The target takes attack damage, sneak attack damage, and suffers the effects of the spell, with the Pactbound spending a spell slot as appropriate.  If the spell requires attack rolls they have advantage to hit, If the spell requires a saving throw the creature hit is at disadvantage for its initial saving throw. If you do not use the sneak attack before the end of your next turn the spell has no effect and the spell slot is lost.

The spell must be of 1st level or higher, have a casting time of 1 action, or require 1 action to activate. Area spells originate at the target point.

You may not use this ability again until you finish a long rest.

Otherworldly Patron

When you reach 3rd level you, you strike a bargain with an otherworldly being: a Fey Power, Fiendish Power, or Shadow Power. Your choice augments some of your archetypes features.

Fey

Your otherworldly patron is a powerful fey or fey-like being.

Fiend

You have a powerful fiend as an otherworldly patron.

Shadow

You have gained a powerful entity from the shadowfell as your otherworldly patron.

Pact Magic

When you reach 3rd level, you can augment your martial skills with arcane abilities granted by your patron. See chapter 10 of the PHB for the general rules of spellcasting and chapter 11 of the Player’s Handbook for the Warlock spell list.

Cantrips. You learn two cantrips of your choice from the warlock spell list. You learn an additional warlock cantrip of your choice at 10th level.

Spell Slots. The Pactbound Spellcasting table shows how many spell slots you have. The table also shows what the level of those slots is; all of your spell slots are the same level. To cast one of your warlock 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.

For example, when you are 8th level, you have two 2nd-level spell slots. To cast the 1st-level spell witch bolt, you must spend one of those slots, and you cast it as a 2nd-level spell.

Spells Known of 1st Level and Higher. At 3rd level, you know two 1st-level spells of your choice from the warlock spell list.

The Spells Known column of the Profane Soul table shows when you learn more warlock spells of your choice of 1st level and higher. A spell you choose must be of a level no higher than what’s shown in the table’s Slot Level column for your level. When you reach 11th level, for example, you learn a new warlock spell, which can be 1st, 2nd, or 3rd level.

Additionally, when you gain a level in this class and subclass, you can choose one of the warlock spells you know and replace it with another spell from the warlock spell list, which also must be of a level for which you have spell slots.

Spellcasting Ability. 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.

Spell save DC = 8 + your proficiency bonus + your Intelligence modifier

Spell attack modifier = your proficiency bonus + your Intelligence modifier

Eldritch Ambush

Beginning at 3rd level your sneak attacks become empowered by the pact with your patron.

You may use your sneak attacks with cantrips that require a ranged or melee spell attack roll, as long as all other requirements are met..

Your patron also enhances your sneak attacks as follows:

Fey Ambush

When you succeed on a sneak attack you may have the target illuminated by strobing, swirling lights. The target loses any benefit from ½  cover, ¾ cover, or invisibility, and the next attack roll it makes is at disadvantage. These effects last until the beginning of your next turn.

Fiendish Ambush

You may have your sneak attack channel the fires of the nine hells. If you do, your sneak attack damage is fire damage instead of weapon damage, and you may reroll any 1s you roll on your sneak attack damage dice.

Shadow Ambush

You may use the power of the Shadowfell to enhance your sneak attack. When you hit and reduce a target to 0 HP with a sneak attack you may absorb some of your target's life force to protect yourself. You gain a number of temporary HP equal to the number of sneak attack dice you roll (½ rogue level rounded up).

Eldritch Whispers

Beginning at 9th level your patron whispers warnings to you in times of danger. When you use your Uncanny Dodge feature you do not have to be able to see the attacker or the attack.
