Shift and Synchronized Strike are creating some (probably) unintentional interactions with gates and gaps through the game. If you get really close to a gate or a small gap that is NOT traversable by just walking and use Synchronized Strike (and sometimes Shift but most of the times only sync strike works) you go straight through and to the other side of whatever its on your way. In the Temporal Sanctum I was able to go through the entire 2 first floors without switching between eras like it is intended. Also, this bug 99% WON’T work in Temporal Sanctum if you are in the Imperial Era and will always work in Ruined. Sometimes when you line yourself pixel perfect to the gate you can go through in Imperial Era but its very unlikely. Some other areas also allow the player to go through small gaps like in Temple Rooftops in Chapter 9. For some reason I can’t upload anything to imgur so here are three youtube videos of footage instead.
