Divination Knight

The service of a diviner is sought by royalty and commoners alike, for all seek a clearer understanding of the past, present, and future. As a diviner, you strive to part the veils of space, time, and consciousness so that you can see clearly. You work to master your vision of discernment, remote viewing, supernatural knowledge, and foresight.

Portent

Starting at 3rd level when you choose this subclass, glimpses of the future begin to press in on your awareness. 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 that you can see with one of these foretelling rolls. You must choose to do so before the roll, and you can replace a roll in 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.

Oracle

By 3rd level, by casting gem-inlaid sticks, rolling dragon bones, laying out ornate cards, or employing some other divining tool, you receive an omen from an otherworldly entity about the results of a specific course of action that you plan to take within the next 7 days. The DM chooses from the following possible omens:

Weal, for good results
Woe, for bad results
Weal and woe, for both good and bad results
Nothing, for results that aren't especially good or bad

The Ritual doesn't take into account any possible circumstances that might change the outcome, such as the casting of additional spells or the loss or gain of a companion.

You regain all expended uses on a short or long rest

You gain a 2nd use of this feature at 10th level

Precognition

Starting at 7th level you can use your reaction to have visions that unravel the threads of space and time. Whenever you or a willing creature you touch make an attack roll, a saving throw, or an ability check, you roll a d4 and add it to the total.

You can use this feature a number of times equal to your Charisma (a minimum of once). You regain all expended uses when you finish a long rest.

When you reach the 15th level, change the die you roll to a d6 instead of a d4

The Third Eye

Starting at 10th level, you can use your action to increase your powers of perception. When you do so, choose one of the following benefits, which lasts until you are incapacitated or you take a short or long rest. You can't use the feature again until you finish a short or long rest.

Darkvision. You gain darkvision out to a range of 60 feet.

Ethereal Sight. You can see into the Ethereal Plane within 60 feet of you.

Greater Comprehension. You can read any language.

See Invisibility. You can see invisible creatures and objects within 10 feet of you that are within line of sight.

Greater Portent

Starting at 15th level, the visions in your dreams intensify and paint a more accurate picture in your mind of what is to come. You roll three d20s for your Portent feature, rather than two.

Foresight

Starting at Level 18 You touch a willing creature and bestow a limited ability to see into the immediate future. For the duration, the target can't be surprised and has advantage on attack rolls,  ability checks, and saving throws. Additionally, other creatures have disadvantage on attack rolls against the target for the duration.

Once the Duration ends, the target immediately goes blind for 1 hour. You can do this once per long rest.
