Vaticinators are an uncommon and unique breed of wizards. Instead of a spellbook, they keep a deck of tarot cards, each inscribed with a spell. They draw from this deck randomly, allowing fate and luck to hand them the correct spell for the situation.

Tarot Deck

Beginning when you select this school at 2nd level, your spellbook tears itself into pieces, each spell morphing into a card within your deck. Your cantrips remain unchanged.

You no longer prepare spells, instead every spell in your deck is considered prepared.

To add more cards to your deck, you follow the rules for Copying a Spell into the Book, Copying from a Spell Scroll, and Replacing the Book as if the deck was a spellbook.

At the end of a long rest, you shuffle your deck and draw a number of cards equal to your Intelligence modifier. You have a maximum hand size equal to 2 x your Intelligence modifier.

At the beginning of your turn, in each round of combat, you draw a card (no action required). You can draw an additional card as a bonus action.

When you cast a spell from your hand, you then put the card into your discard pile. At the end of a short or long rest, you shuffle all cards from your discard pile back into your deck.

Read the Cards

Whenever you cast a spell from your deck, you may choose for it have an additional effect depending on the school of magic it originated. If you choose to do so, it consumes your reaction.

Conjuration. Draw a card.
Necromancy. Instead of discarding the card, you take an amount of necrotic damage equal to the spells level. If you do, return the card to your hand.
Evocation. Deal an amount of damage to a target you can see within 60 feet of you equal to the spells level. This damage can be in the form of cold, fire, lightning, acid, or poison.
Abjuration. You or an ally you can see within 60 feet of you gains a number of temporary hit points equal to the spells level.
Transmutation. Choose a card in your hand and shuffle it into your deck, then draw a card.
Divination. Look at the top card of your deck, you can choose to either leave it there or move it to the bottom of the deck.
Enchantment. Target creature you can see within 60 feet of you must succeed on a Wisdom saving throw against your spell save DC. If they fail, choose one of the following effects:
     - The target is charmed until the start of their next turn.
     - The target is blinded until the start of their next turn.
     - The target is deafened until the start of their next turn.
Illusion. Discard any number of cards, then draw that many.

Stacking the Deck

Beginning at 6th level, you can manipulate your deck through shuffling.

You gain proficiency in the Sleight of Hand skill, and your proficiency bonus is doubled for any ability check using Sleight of Hand.

Additionally, whenever you shuffle your deck, you may search your deck for a number of cards equal to half your Intelligence modifier, rounded down, and set it aside. Then after you complete the shuffle, you place those card on top of your deck.
