Espyo | Luna teleport glitch - Fire Emblem Awakening @srb2Espyo | Uploaded October 2016 | Updated October 2024, 8 hours ago.
Some people have had reports of characters using Luna, or other such skills, blazing past the enemy in their animation, and then suddenly teleporting back to the starting position.

I think I've found a consistent way of doing this. If you've got a Great Knight activating Luna on an enemy, then having a Dual Strike trigger or a second attack, while on Origin Peak (chapter 25's location), this should happen to you.

Apologies for the video quality, and for switching camera modes at the start.
