The Seer

Your patron is a being that sees into what is meant to be unseen and beyond, a creature that sees through time and, perhaps, into different realms. Usually, these entities are entirely mysterious, able to avoid detection and understanding, as they can always see the attempts coming and avoid them.

This being's motivations and plans will often be impossible to fully understand until they come into fruition, as they act to set up the pieces to reach a specific future that they can see. Those who make pacts with these mystifying patrons often wish to gain knowledge needed to forge their own fate or to change a destiny they don't with to be dealt..

Future Spell

Your patron allows your mind access to magic from an alternative future. You learn a spell that is on your Expanded Spells List that is of a level you can cast called your Future  spell. You know that spell and it doesn't count against the number of spells you know, and you can cast it as a ritual if it has the ritual tag.

Additionally, when you gain a level in this class you can choose one of the spells from your Expanded Spell List and replace your Future Spell with it, so long as it is of a level you can cast.

Gifted Sight

You gain the ability to view glimpses of possible futures and partially manifest them in your timeline. You have a pool of d4's that you can spend to aid you and your allies. the number of dice in the pool is 1 + your Warlock level.

When you or a friendly creature that you can see within 30 feet of you makes an attack roll, ability check, or saving throw, you can use your reaction to roll a d4, adding the number rolled to the result by spending a die from the pool. You can choose to use this feature after the creature makes it's roll, but before the DM determines if it succeeds or fails. 

Your pool regains all expended dice when you finish a long rest.

Alter Fate

You can look at potential futures and alter fate's current course to hinder your enemies. When a creature you can see within 30 feet of you makes an attack roll against you but before the the result is announced, you can use your reaction to roll 2d4. The creature gains a penalty to it's roll equal to the result, and it is Marked by Fate for 1 minute. While marked in this way, you can roll a 2d4 rather than a 1d4 when using your Gifted Sight feature to aid a creature making an attack roll or ability check against it. 

Once you use this reaction you cannot do so again until you finish a short rest.

Allseer's Mind

You're gift of sight reveals what is hidden to you. you are always under the effects of the see invisibility spell unless you choose not to be, you are immune to being blinded and cannot be surprised while you are conscious. 

Impeccable Foresight

You are able to activate your power and see the immediate future. As an action, you can give yourself this foresight for 1 minute. For the duration, you have advantage on attack rolls, ability checks, and saving throws. Additionally other creatures have disadvantage on attack rolls made against you for the duration.

Once you use this feature, you cannot use it again until you finish a long rest.
