Last Wish

Last Wish is a Raid in Forsaken, taking place in the Dreaming City. It is the culmination of the expansion's storyline, and is described as being "like the Vault of Glass and Dreadnaught had a baby." It has the most bosses for a raid yet in Destiny 2. It takes place in an escalating series of encounters throughout the Dreaming City, before culminating within the Keep of Voices, the tower at the head of the Dreaming City.

Bosses

 * Kalli, the Corrupted
 * Shuro Chi, the Corrupted
 * Morgeth, the Spirekeeper
 * Riven, of a Thousand Voices

Kalli, The Corrupted
Guardians will enter a large, empty chamber. The layout is similar to the Blind Well because of the central pit, varying platforms and eight plates around the area. Near the center pit, six icons will appear, with two of each: Heads (two-headed snake), Smile (a snake in a smiley face pattern), Eight (an eight sign), and Infinite (the infinity symbol). One icon will not be shown. There will be a matching plate for each of the icons (I.e. Heads, Eights, and Smiles being shown. Two of each Smile, Head, and Eight plates must be captured. Each plate will have their symbol above or near the side of the plate. Each plate is divided into three sections. Two Taken Blight bombs will be above two of the sections. Stand on top of the empty section of the plate and defend as Taken Thrall and Taken Psions attempt to overwhelm the team. If a plate is held long enough, an Eye of Riven will spawn. Killing the Eye of Riven is not required but helps to greatly guarantee survival in the damage phase.

Also be cautious, as Kalli will be immune and warp to a random plate and attack with blasts similar to a Taken Hobgoblin's defensive bolts. Shortly after each plate has been captured, Kalli will enter the room's center area and attack with bolts and an ability similar to a Psions Psionic Blast. After most of the first segment of her health depletes, she will cast her weapon which will wipe the team. Upon her spell being cast, each Guardian must immediately run into one of the open doors on the side of the well, which are tied to the Eye of Riven enemies. Ensure that you kill an Eye of Riven to guarantee that a door will be open, or you will be wiped.

Challenge Mode
You must cleanse all nine plates, including the plates of which symbols do not match with any of the six shown in the center. Doing so will spawn an ogre per wrong plate (three total).

Shuro Chi, the Corrupted
When you first get to the door of the arena, it will be closed. To open it, the whole team must stand at the door. To the right of the door (before you enter), there is a big rock that you can jump on to get into the arena before the fight starts, allowing you to get a better understanding of what you need to do. Most of this fight is about managing supers, as there are lots of ads. Dawnblade and Orpheus tether are extremely good for this, as tether makes the orbs and Dawnblade get kills - making more orbs. Whisper, Sleeper, and the Ikelos SG are extremely good for boss DPS, and a Well of Radiance will only increase that DPS.

Now that you have your loadout setup, it is time to begin the fight. When you first enter the room, Shuro Chi will be directly in front of you, and will begin a song. You have around four minutes to complete each floor, before the song kills you. Each time you complete a floor, the timer resets. She will teleport a few times to the left, before resting in a specific area. While she does this, tons of ads will spawn. You can not take down her shield until all of them are dead, so they are priority one. Among these ads, there is one yellow health captain called the Eye of Riven. This ad will be seen for most of the raid, and every time it will drop an object upon being killed. You will want to leave this on the ground until Shuro Chi's shield is down, as you will build up stacks of a debuff that, much like greed from Spire of Stars, will kill you after a certain amount of stacks, but rather than 10, it is 5. This debuff will stay for a certain amount of time, so you will need 2 designated players to carry this eye, alternating for each of the 6 phases. After killing all the ads, three crystals will spawn on three plates. While you stand on the plates, you will take damage. You need to have three people pick these crystals up and shoot them at the person hold a crystal to the right (or left, you just all need to shoot in the same direction), making a sort of triangle. This will break her shield allowing you to do damage. You want to do the crystal part fast, as her song's tempo will quicken until you break her shield. Now, if you look down at her health bar, it will have six different bars of health. After breaking her shield, she will begin the obliterate attack that Kalli used. You need to destroy one bar of health to stop her from obliterating you. This is where you pick up the thing that the Eye of Riven dropped. When you pick it up, you will see that you have your Super charged immediately. Using this near Shuro Chi will cancel the obliteration sequence, and she will start it again. You need to use your super right next to her as late as possible, allowing you to give your team as much time as possible to shred the bar of health. After you use your super, the artifact will disappear, and you join your team with DPS. After you get down a bar of health, her shield will go back up, and she will teleport to the next area (still on the same floor). Once again, kill ads and break shields. The other person who is supposed to pick up the artifact will use it to cancel the wipe, and she will teleport again. The only difference is that there is a yellow health Taken Ogre that you want to kill.

Now, the next place Shuro Chi teleports to is up a floor. You need to fill 3 sorts of jigsaw puzzles. You will see three circles on the walls. Each of these will show part of a symbol, starting with the one on the left. In the middle of this area, you will see nine plates. These plates, like the last ones you stood on to break Shuro Chi's shield, will deal damage. You need to stand on the plates corresponding to the empty parts of the symbol to fill the symbol. There will be 4 people doing this, and the other two will be taking care of the ads in the room, prioritizing the phalanxes. This is because after you stand on the plate, you cannot stand on it again, so if a Phalanx knocks you off, you cannot get back on. After filling all three symbols, you can move upwards, and rinse-and-repeat for another two floors. Keep in mind that the song does not reset until after you fill the symbols, not after the second phase of damage on the floor, and starts immediately after.

Wall of Wishes
The Wall of Wishes can be found right before the Kalli encounter. It consists of 21 buttons, when shot, will change to a different symbol. There are fifteen wishes that can be activated for the raid:

Trivia

 * Guardian activity during the raid will change the actual Dreaming City destination throughout the first few weeks.
 * The raid is the third to take place in the Ascendant realm, the first being Crota's End, and second being King's Fall.
 * A set of lore tabs in Forsaken offers an explanation as to why Last Wish in particular can be repeated ad infinitum in canon, claiming that Quria, Blade Transform, now attempting to defect from the Taken, trapped the entire area in a timeloop to buy time to undo the corruption of the wish that Riven, the last Ahamkara, granted. However, as these texts belong to an arc involving unreliable narrators, the veracity of this claim cannot be verified, especially since the messenger of said lore series is claimed at different points to be Quria, Eris Morn, the Computer Core Medusa, and Dûl Incaru.
 * The raid is the first to ever feature an Ahamkara as a boss, and also the first to take place in the Reef.
 * For a short period of time, it was possible to glitch into the environment that the raid existed in and open a raid chest without being in the raid. However, this was disabled by Bungie.
 * The world's first clear of the raid was performed by Clan Redeem in 18 hours and 48 minutes. Their achievement triggered a change to the Dreaming City, causing it to become corrupted by Riven's last wish.
