Mark of the Outsider

Directly inspired by the game series; Dishonored by Arkane Studios.

The Outsider bears a great interest in mankind's acts. It's all a game for Outsider, for him to be entertained and amused. For those he deems truly interesting or sees potential in, he may just give them an ounce of his immeasurable power. The Outsider is an considered an Eldritch God that lives outside of our understanding. The Outsider may visit when you dream, or even as a mirage when you're awake. He may leave bits of info or foreshadowing on to what is to come, but one thing is for certain; he is watching.

The Mark of the Outsider sub-class draws it's magic from the Void in the form of Void Magic and a Mana Pool. The Void Magic divides into two categories, Active and Passive Powers. Active Powers cost Mana and are immediate effects (and count as spells for purposes of dispel magic and counterspell), whereas Passive Powers will remain and exist no matter how much Mana you have, you can always fall back on them. All Active Powers require a Mana Cost that is specified in their description, and you gain different Powers at different levels.

Spellcasting

When you reach 3rd level, you gain the ability to cast spells - but you do not use them conventionally. You cast spells from your Void Magics list, using Mana. See Spells Rules for the general rules of spellcasting.

Spellcasting Ability

Charisma is your spellcasting ability for your Void Magic, since you have inherited your powers from the Void. You 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 any Void Magic you cast and when making an attack roll with one.

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

Spell attack modifier = your proficiency bonus + your Charisma modifier

Mana Pool

The Mark of the Outsider bestowed upon you a wondrous gift. Void Magic. You channel the Void through you, and as such, you can cast your Void Magic and expend Mana.
At level 3, your Mana Total is equal to double your Rogue Level, and it recharges on a short or long rest.

Void Magic

When you choose this archetype at 3rd level, you learn four Void Magics of your choosing (one must be Warp or Far Reach, you can choose both).

All Active Powers can be activated for their Mana Cost and cast with the specific rules integrated into the description, every Active Power is intended to be treated as a spell.
All Passive Powers can not be deactivated, dispelled or counterspelled.

You gain three more at levels 9 and 13.

Bloodthirst

Pre-requisite Level: 3
Mana Cost: N/A

You can now activate a modified version of the Barbarian's Reckless Attack.
You can throw aside all concern for defence to attack with fierce desperation. When you make your first attack on your turn, you can decide to attack with an unsatiated bloodthirst. Doing so gives you advantage on melee weapon attack rolls using Dexterity/Strength during this turn, but attack rolls against you have advantage until your next turn.

When you defeat a creature while Bloodthirst is active, you gain temporary hit points equal to your CHA modifier.

Bloodthirst is an Enhancement Void Magic, and as such, this costs nothing to activate.
