Trial of Lingering Pain
Trial of Lingering Pain is one of the Trials of Ascendancy, and is found randomly in Maps. It demonstrates Blade Sentrys, which are very wide traps that move along set paths taking player's energy shield and health quickly when cut by them, enough to kill in roughly one second. The damage does not depend on difficulty, but the layout is harder on higher difficulties.
Upon completing the trial, Izaro gives the message "An emperor must wear two blades. Hope in the left hand, Surety in the right." and you are provided with a portal back to the entrance.
