The Other

Your patron has come to you in dreams your entire life. Many of these dreams are troubling and ominous, while others are prophetic and insightful. Only very recently has your patron stepped forward in these visions and made themselves known innately to you: your patron is yourself (or the posterity of your bloodline). Presumably from the future - an alternate reality or perhaps the very same - they have attained enough power in their present to be capable of sending you magical gifts backward through time.

These gifts manifest as raw, pure arcane power, not filtered through elemental or divine magic or other similar dampers on your latent power. Power centered on harnessing and manipulating this force magic in various ways - such as shielding and protections, altering the flow of time, teleportation, as well as devastating blasts and giving destructive forms to this arcane force.

While that much is clear, their motives and actions are not. Their intentions could potentially be genial, wishing to ensure that you thrive enough to ensure their reality. Or, perhaps they have more sinister machinations and unresolved business in the past that they desire to change, using you as the catalyst. One thing is for certain though - someone from the future is looking out for you.

Visions Of The Future

Starting at 1st level, you receive brief glimpses of the future, a side effect of communicating with your patron in dreams. When you finish a long rest, roll two d20s and record the numbers rolled. You can replace any attack roll, saving throw, or ability check made by you or a creature you can see with one of these foretelling rolls. You must choose to do so before the roll, and you can replace a roll this way only once per turn. 

Each foretelling roll can be used only once. When you finish a long rest, you lose any unused foretelling rolls and roll two new foretelling rolls.

Limits Of The Arcane

Starting at 1st level, you learn the Sword Burst cantrip, which counts as a warlock cantrip for you. 

Your patron's tentative and strained bond to you, coupled with their preference for pure arcane force, limits your own scope of spellcasting. You can only cast spells that deal damage if the damage type is Force. Spells that do not deal damage are not affected by this restriction.

Tempered Power

Starting at 6th level, your patron allows you to directly tap into their power through your bond whenever you choose. When you cast a spell with a spell slot that deals Force damage, you can add your Charisma modifier to one damage roll of that spell.

Imminent Clarity

Starting at 10th level, your patron solidifies your bond to their reality, further improving your perception of future events. You roll three d20s for your Visions Of The Future feature, rather than two.

Absolute Power

Starting at 14th level, your patron bestows an immense amount of their own personal arcane power upon you, directly tethering their fate to your own. Spells you cast ignore resistance to Force damage. In addition, when you roll damage for a spell you cast that deals Force damage, you can treat any 1 on a damage die as a 2.
