==== Description ====
The Chronokey is a legendary artifact imbued with the power to manipulate time itself.

The Chronokey has an aura of immense magical power, and its surface is engraved with runes representing the flow of time.
=== Activation ===
Activate: Command (1 action)
Frequency: Once per day
=== Properties ===
# Temporal Manipulation (Necromancy, Transmutation): When you activate the Chronokey, you can choose one of the following effects:
#* Time Stop: You stop time for everyone but yourself for up to 3 rounds. During this period, you can take actions as usual, but you cannot affect creatures or objects other than yourself and those you're carrying.
#* Temporal Regression: You can rewind time by up to 1 minute. Everything reverts to its state at that time, except you and the Chronokey. You retain memories and any changes to your status and position.
#* Accelerate Time: You can speed up time within a 30-foot radius for 1 hour. All creatures and objects within this area experience time at twice the normal rate. This does not stack with other effects that speed up time.
# Chronomancer's Insight (Divination): While holding the Chronokey, you gain a +5 insight bonus to Perception checks and initiative rolls. You can also use the following spell-like abilities at will:
#* Augury (Divination)
#* Clairvoyance (Divination)
#* Divination (Divination)
# Temporal Shield (Abjuration): As a reaction, when you would be hit by an attack or targeted by a spell, you can activate the Chronokey to gain a temporary shield. This shield gives you a +4 circumstance bonus to AC and saves until the end of your next turn.
# Timewalker's Agility (Transmutation): Once per day, you can activate the Chronokey to gain the effects of the Haste spell for 10 minutes. Additionally, during this period, you can move across difficult terrain without penalty and are immune to any effects that would slow you down.
# Paradox Prevention (Abjuration): The Chronokey can prevent paradoxes by negating effects that would create temporal anomalies. Once per week, you can use the Chronokey to cast Wish with the specific purpose of maintaining the stability of the timeline.
=== Destruction ===
The Chronokey can only be destroyed by performing a complex ritual at the heart of a temporal anomaly, such as a time rift or a planar breach involving the Plane of Time. The ritual requires the cooperation of a chronomancer of at least 20th level and the use of another artifact of equal power to create a stable paradox, which will then consume both the Chronokey and the artifact used in the ritual.
