School of Astronomancy

The heavenly bodies and celestial movement of them have garnered the attention of many races throughout history. Such is the pull of Astrology, that few are blessed with a unique gift to divine the stars' intent. Those selected few are known as Astronomancers and wield fate not unlike Diviners. However, Astronomancers take a more direct approach, influencing the outcomes by their own hand.

You gain proficiency in Intelligence (History).

Additionally, you learn the Starlight cantrip. This does not count towards your number of cantrips known.

Celestial Deck

2nd-level School of Astronomancy Feature

You gain a Celestial Deck, a tool used by Astronomancers to divine heavenly movement. You can use the Celestial Deck as a spell casting focus for your Wizard spells. If you lose your Celestial Deck or if it is destroyed, you can perform a 1-hour ritual in which you recreate the deck through magical means. This ritual can be performed during a short or long rest. You can only have one Celestial Deck at any time.

Your Celestial Deck comes with two Heavenly suites: Solar and Lunar. When in-combat or in a hostile encounter, you use and draw from the Solar suite. When out-of-combat or in passive encounters, you use and draw from the Lunar suite.

While the Celestial Deck is on your person, as a bonus action, you can roll a d6 to draw and play a card with certain abilities. To play a card, you must target a friendly creature that you can see, to include yourself. You then apply the card's benefits to that chosen creature.

Solar Suite

d6	Solar Cards
1	Wall: +1 to AC and resistance to one damage type of your choice
2	Sword: Gain advantage on next attack roll
3	Wings: The next attack roll against the affected creature has disadvantage
4	Ewer: Gain 1d6 + your Wizard level in temporary hit points
5	Mirror: The next time the affected creature is hit, the creature takes 1d4 + your wizard level points of the same type of damage used against it
6	Coin: Gain advantage on next saving throw

 

Lunar Suite

d6	Lunar Cards
1	Fort: You may remove one condition or disease from the affected creature as if it is targeted by the lesser restoration spell
2	Arrow: Gain +5 to passive perception and investigation
3	Feather: Receive the effects of the jump spell and take no bludgeoning damage from falls
4	Sieve: Affected creature may spend a hit die as a bonus action to heal hit points as if taking a short rest
5	Glass: Gain proficiency in a skill of your choice
6	Gem: Gain advantage on next ability check

 

A creature can benefit from Solar and Lunar cards once. In order to receive these benefits again, they must complete a short or long rest.

You can draw and play from each Heavenly suite a number of times equal to your proficiency bonus. Solar cards last for either 10 minutes, the card's effect has been met, or until the hostile encounter is over. Lunar cards last for either 10 minutes, the ability is activated, or the affected creature takes a short or long rest.

You regain uses of this ability when you finish a long rest.

You learn to weave greater celestial magic into your cards. You learn the augury spell. It is always prepared and doesn't count towards the number of spells you have prepared. Once per long rest, you can cast this spell without expending a spell slot, provided you have your Celestial Deck available.

In addition, you are able to extend celestial energy further when utilizing cards from your Celestial Deck. When you play a card on another creature, choose a friendly creature, to include yourself, within 30ft. Both creatures gain the effect of the card. You can use this ability a number of times equal to your proficiency bonus and regain all uses after a long rest.

At 10th-level, this ability also extends to your Eclipse Deck.
