Wanna do it ? I teach it often lol... So, you're talking first encounter. When the encounter begins, two things happen : (1) there's a timer called "Engulfed in Darkness" which will wipe the whole team if it runs out. You reset the timer by depositing the chalice in the preserve bowls. The bowls are mandatory to proceed with the encounter. The Lanterns along the path serve as an extra way to reset the timer if you're not reaching the bowls fast enough. Lanterns are optional, and you must be enlightened to active a Lantern & reset the timer. You get enlightened by having a player take the Chalice from you, once your bar is fully charged. (2) Each player will individually get "Weight of Darkness" which slows you down & prevents you from double-jumping or sprinting. It maxes at 10 stacks of slowing, but will not kill you. Neither holding the Chalice nor being Enlightened will affect the Weight of Darkness. There's 2 ways to remove/prevent your Weight of Darkness, aside from getting dead. One is to be near a Lantern when it gets activated. As the Lantern lights up, it removes your Weight of Darkness, but dont stay too long. The Lantern will turn from white to red then blow up & kill anyone near it. The 2nd and less-known way is to be standing on a plate. If you pick up the Chalice & just stand on the starting plate, you'll never gain Weight of Darkness. Similarly, if you make it to the end of the path & stand on the ending plate, you will not have Weight of Darkness.
