Citations for Purported Echo Abilities

[Wyssahtyn]

Those seem more like fan theories to me to explain game mechanics.

This was my assumption as well. The only explanation the AoE markers have ever been given that I can find was in the Hall of the Novice wherein it's explained that the PC is simply reading the enemy's tells, no Echo involved. And the dungeon wipes thing I've yet to really find any citations on, simply people repeating it as fact.

Simply wanted to know if anyone here knew of any proper sources.
