Time Strategist

 

You gain an extra reaction in combat. 

Spellcasting Potency

You add your Wisdom modifier to the damage or healing dealt with any cantrip. (if you already add it, add it twice)

Channel Divinity: Time Halt

You can buy yourself extra time.

You have an extra 2 hours of the day, granted by your goddess. If you activate the spell e.g. at midnight it can seem like midnight lasts an hour. No-one knows why. That way you can buy yourself a 26-hour long day.

You can for example activate the spell for only 5 minutes at a time, several times a day, or for up to 2 hours at once. The 2 hours time reserves for you to use refresh at 6:00 AM. 

If you channel divinity for less than 1 minute you can completely halt everyone's actions. Halting time that way requires a 1 hour cool down to use in that way again.
