You cast hold person on an echo knight with manifestation out. The knight fails his save. What happens to the echo, and what are its options? My ruling is if the echo is out before you’re held it can do things freely, but you can’t manifest it while held. I want to make sure I didn’t miss anything and what the hive mind thinks.
A basic way to think about it, irrespective of the incapacitated bit, because the Knight attacks through the Echo, if the Knight can’t attack for whatever reason, neither can the Echo, whether it disappears or not.
