How is the Mystic's Darkness ability supposed to work?

[Takai153]

So I started playing d&d a few months ago and have now begun looking at unearthed arcana stuff. The Mystic class has me really interested, however their version of the darkness spell has me really confused. It doesn't give a duration for it, which was said in the beginning of the pdf that anything without a listed duration was instantaneous. So doesn't that mean that it just creates a bubble of magical darkness for a moment and then it goes away before you can do anything? Is there anyway to make use of this that I'm missing?

As per Sage Advice (https://www.sageadvice.eu/2017/03/14/mastery-of-light-and-darkness-has-no-specified-duration/), it should be concentration up to 1 minute, like the light effect.

Thank you.

RAW, it's either instantaneous or permanent depending on how you read it. RAI, and as Grod put above, it's supposed to function similar to the light ability.

Great, JC doesn't think the duration should even match the darkness spell.

To be fair, it DOES come bundled with see-through-magical-darkness.

Just as with Light spell; Its just the opposite of the same spell in effect really.

Same with Cure/Cause wounds, Heal/Harm, Open/Close, etc., it just follows the opposite spell's data usually.
