Destiny 2s Forsaken expansion gave each class three new subclass skills trees that could interfere with the game's long-lived aliens. Compared to the original subclass trees, the new ones are more tasteful and synergistic, plus each has a powerful new superflow. So you will want to unlock them ASAP.
To unlock your first subclass tree
To unlock your first subclass, just play through the campaign in Forsaken. After you have removed the first mission, enemies begin to release feather-like elements called Visions of Light. These appear as small lights on the ground. Be sure to pick them up. When you collect 1
Tough enemies drop more visions of light, to speed up this gate, look for public events in Tangled Shore as you review the story. These are filled with orange and yellow-bar enemies that release many visions. Once you've collected 100 visions, complete the IO mission as soon as possible so you can level your new subclass while playing through the rest of the campaign. You only get the new super first, but when you take care of super and grenade damage, you get access to the tree's melee and passive abilities as well.
To unlock your second subclass tree
You will not find more lightvisions after you received your first listing. But you can get a second Seed, it takes a bit more effort. Start completing the Forsaken campaign and after completing the final mission, talk to Petra and Spider in Tangled Shore to start the mission that unlocks the Dreaming City area. It's a simple task, just follow the instructions in the game and you'll bash it pretty quickly.
Your goal is the Blind Well activity in Dreaming City. The Blind Well is divided into four levels based on difficulty. The tier-two, 540-light version of the well can drop you another light, so you have to play it again until you get one. You will need teammates for the well and you will be at least light level 515 for the tier-two version.
You can start a tier-two vel by depositing the right "fee" in the center of the arena. If you do not have the right fee at hand, you can buy one from Petra in Dreaming City using Dark Fragments, which you can get by completing other activities around the city. Failure to find a teammate who has a tier-to-charge. You can receive a candle light from a round even if you do not charge the fee yourself.
The blind well is a fairly simple horde mode, not different from the Mars & Escalation Protocol. When you start a round, enemies will wander in waves. You have to kill enough enemies to fill the progress bar within each wave's time limit, but there are some other things to keep track of. Initially, keep yourself within bubble-like shields that are dotted around the well to maintain the Touch of the Sky buff that protects you from the Touch of the Deep debuff. These bubbles move after each wave, so keep an eye on the next one.
You will also meet glowing, apparently invincible enemies in the well, called the plague servants. To kill these servants you must kill glowing enemies called Anathema. Anathema drops glowing orbs that give a buff called Harmony when they are fetched. Harmony allows you to protect the shields of servers and also significantly increases the supercharging rate. To kill Anathema and grab Harmony orbs is particularly important for the final round of the well where shielded abuses are given along with several Anathema. Deal with them in the same way as the servants: kill Anathema, grab their Harmony orbs, and break some shields.
Currently, you can significantly increase the speed of the Blind Well gate using a bug involving the exotic fusion gun Telesto. Telesto shoots projectiles that explode after a short while, and for some reason Blind Well detects these explosions as enemy kills. In other words, by shooting a few fills with Telesto, you can maximize the wave propulsion gauge in a moment. This is a mistake, mind, and one that will certainly be squashed soon, but you can still use it while it lasts.
To unlock your third subclass tree
When you receive a candle light from the Blind Well, you can not get another on that character. And at the time of writing, no one has found a way to unlock all three new subclasses on the same character. As such, many players believe that the next candle light is linked to Dreaming City's raid, Last Wish, which launches Friday 14th. September. Bungie says that the raid will change Dreaming City and its activities, so it is likely that we will only be able to unlock all three subclasses when Forsaken enters its third week. We update this guide with more information as new methods are revealed.
