Nightingale Legacy Portal
In the Harbarium Site of Power, in the fight agains the big automaton at the top, he hit me and throw me down out the dungeon and I don't die. When I re-enter and climb it up back, the boss and 3 minions just stood there doing nothing so I kill them all taking my time.
Did this unlock the echo though? This happened to me and i was unable to collect the herbarium card
