Monty's exact note on the flash from when Cardin punched Jaune was "First hints of a Semblance." in the volume 1 director's commentary.

Edit: Anyway, I agree with Spirited that it probably bounces damage back at the enemy, like a reflect spell in a JRPG. Could be why Cardin's hand was hurting. Either that, or it could blast enemies away from him like that one bit in WoR: Aura where a generic silhouette blasts a pile of Beowolves off of him when Salem says "Semblance." I thought relic and artifact were synonymous with each other.
