Will there be a Reverse Dunamancy spell to allow time travel? Because I don't believe D&D has fully explored the possibilities of time travel in magic. pic.twitter.com/LoMDe1c8nN

Not to mention a nightmare to DM.

A quick counterpoint: If it’s fantasy and not science, that means it’s not exact. Much like how when you use teleport without a circle destination, you have to roll % dice on the success. I think it would be an interesting addition with limitations and ways to gloriously fail. There are many ways to introduce such ideas to a home game! Time travel as a player-spell (particularly when it comes to going BACK in time) becomes a challenge to balance and make trackable on a mechanical level. Narratively…hell yeah, go for it!
