# Artificer Specialty: Horologist
The practice of horology, or the study of time, is an intricately delicate task. The inner workings of clocks and other timekeeping devices requires precise tools and a keen mind. Artificers who practice horology are capable of creating magical machines which can replicate effects on a regular basis, or to record events and alter them.

### Tool Proficiency
*3rd-level Horologist feature*

You gain proficiency with jeweler's tools. If you already have this proficiency, you gain proficiency with one other type of artisan’s tools of your choice.

### Horologist Spells
*3rd-level Horologist feature*

You always have certain spells prepared after you reach particular levels in this class, as shown in the Horologist Spells table. These spells count as artificer spells for you, but they don’t count against the number of artificer spells you prepare.

##### Horologist Spells
| Artificer Level | Spell |
|:----:|:-------------|
| 3rd  | Alarm, Gift of Alacrity |
| 5th  | Cloud of Daggers†, Wristpocket |
| 9th  | Haste, Slow |
| 13th | Death Ward, Mordenkainen's Private Sanctum |
| 17th | Greater Restoration, Temporal Shunt |

† Instead of daggers, a cloud of whirring gears appears, dealing bludgeoning damage in place of slashing.

### Timekeeper's Pocketwatch
*3rd-level Horologist feature*

Your horological studies allows you to tinker with precision machinery and chronomantic magic in order to produce a magical trinket which allows for timekeeping and magical control. When you finish a long rest, you create the Timekeeper's Pocketwatch, a tiny object that you carry on your person. The Timekeeper's Pocketwatch keeps a perfect record of the time and acts as a spellcasting focus for your artificer spells.

The Timekeeper's Pocketwatch allows you to manipulate the flow of time around you. As an action, you can choose to accelerate or decelerate the flow of time for 1 minute.

While the flow of time is accelerated, you gain the following benefits:
* Your speed increases by 10 feet.
* When you cast a spell of 1st-level or higher, you can cast a cantrip as a bonus action.
* You gain a bonus to your AC equal to your proficiency bonus.

While the flow of time is decelerated, you emit a bubble of chronomantic energy around you in a 15-foot radius sphere, creatures other than yourself in this sphere gain the following penalties:

* A creature's speed is reduced by 10 feet.
* Creatures can only take an action or a bonus action on their turn, not both.
* A creature's armor class is reduced by an amount equal to your proficiency bonus.

You can use this feature once per long rest, unless you expend a spell slot of 1st level or higher to use it again.

### Chronological Adjustment
*5th-level Horologist feature*

Your adjustments to the Timekeeper's Pocketwatch allows you to manipulate the duration of magical effects, both beneficial and harmful. While the Timekeeper's Pocketwatch is on your person, as a bonus action on your turn, choose a magical effect with a duration longer than Instantaneous that you are aware of. You can choose to increase or decrease the effect's duration by a number of rounds equal to your Intelligence modifier (one round is 6 seconds). 

You can use this feature once per short or long rest, unless you expend a spell slot of 2nd level or higher to use it again.

### Time Loop
*9th-level Horologist feature*

You can cause an isolated time loop for spells you cast while you possess your Timekeeper's Pocketwatch. When you cast an artificer spell with a duration of Instantaneous, you can expend an additional spell slot to initiate a time loop for the spell. For a number of rounds equal to the additionally expended spell slot's level, the spell you cast is repeated at the start of each of your turns (minimum of 1 round).

### Rewind
*15th-level Horologist feature*

Your mastery of the horologist's art allows you to record a temporal image of yourself into your Timekeeper's Pocketwatch for emergencies as an action. The temporal image records the amount of hit points you had at the time of recording and the amount of hit die you possessed.

The next time you are reduced to 0 hit points, your Timekeeper's Pocketwatch rewinds your personal timeline to the point you recorded the Temporal Image. The world's timeline isn't rewound; you don't move, nor does anything around you change, you merely revert to the status you had at the time of recording.

When this ability activates, make a DC 25 Constitution saving throw. On a failed save, you gain 1d4+1 levels of exhaustion due to the massive strain the magic puts on your mind.

Once you use this feature, you can't use it again until you finish a long rest.
