There are nine different subclasses to choose from in Destiny 2, and for the most part, they play severely different from each other.
The Warlock subclasses have some consistencies between them, but digging deep shows they really do what they do in different ways. For this list, let's take a look at the Voidwalker subclass and how to get the most out of it in Crucible.
10 NOVA BOMB
Unless you've selected the Attunement of Fission, the supercharge you're going to have for the Voidwalker is the Nova Bomb. This is a one-shot on any Guardian, including those that have an active super (in almost every case). It takes a second to throw out, and you're pretty exposed while you do so, so make sure you're not at super low health. It's generally a bad idea to do this in front of a sniper.
9 GRENADES
The grenades available to the Voidwalker subclass are the Vortex Grenade, Axion Bolt, and Scatter Grenade. These can all be pretty strong choices, as grenades are one of the strongest points of the Voidwalker, but let's take a look at the strengths of each.
The Vortex Grenade creates a sphere of damaging Void energy wherever it lands. The sphere deals constant damage to enemies it's in contact with, making it a great way to cut off a lane or to keep an enemy from capping a point in Control.
The Axion Bolt detonates on contact with a surface, releasing bolts of Void light that track nearby enemies. This is relatively similar to the Gunslinger's Swarm Grenade, though the Void bolts won't sit in place and wait for an enemy to stroll by.
The Scatter Grenade splits into a bunch of small Void explosions upon coming into contact with a surface, making it a great way to blanket an area in immediate damage, and ensuring an enemy isn't likely to dodge the damage, either.
8 MELEE
The melee ability for the Voidwalker is pretty similar no matter the Attunement you choose. It has a pretty surprising range and can have a variety of positive benefits, from fully regenerating your health to creating a Void explosion that recharges your grenade.
7 RIFT
All Warlocks have the same two Rifts to choose from, Healing or Empowering. The Healing Rift continuously heals you and allies inside of it, making it a great way to lock down an area for a short while.
The Empowering Rift increases the weapon damage of you and allies inside, which isn't usually going to be as useful as the healing but has its place.
6 GLIDE/BLINK
In Crucible, the Warlock's weakness lies in its mobility abilities. Thankfully for Voidwalker's, they have things a little bit better; they get Blink. Blink teleports you a short distance, allowing you to close a gap on an enemy without giving them a chance at dropping you along the way. This is fantastic for builds that rely heavily on melee and/or shotguns.
The other two Voidwalker mobility abilities are Strafe Glide and Burst Glide. Strafe Glide gives you a bit more directional control in midair but can leave you a super easy target. Burst Glide gets you where you're going a bit quicker, so if you don't like Blink, this is usually the choice to make.
5 ATTUNEMENT OFÂ HUNGER
Attunement of Hunger has the abilities: Devour, Feed The Void, Vortex, and Insatiable. Devour fully regenerates your health with a melee kill, with additional kills restoring more health. This is an incredible ability for Crucible, allowing you to even the playing field in outnumbered engagements better than perhaps any other ability in the game.
Feed The Void allows you to consume your grenade energy to regenerate your health, granting you the Devour effect. This can get you out of sticky situations, and, once again, allows you to take outnumbered engagements with a bit more confidence.
Vortex creates a Vortex Grenade at the impact point of a Nova Bomb. This isn't super beneficial for Crucible as enemies are almost always one-shot by the Nova Bomb, but it can keep enemies from coming back into the area for a while.
Insatiable goes hand in hand with Devour. While the Devour effect is active, killing enemies extends its duration and recharges your grenade. This can essentially create an infinite loop of Feed The Void and Devour and can go a long way in sustaining those We Ran Out Of Medals streaks.
4 ATTUNEMENT OF FISSION
Attunement of Fission has the abilities: Nova Warp, Atomic Breach, Dark Matter, and Handheld Supernova. Nova Warp replaces the Nova Bomb as your super, instead of giving you a roaming super. This allows you to fire a beam of Void light at targets, dealing heavy damage over time to them, though it's a bit less powerful than most other roaming supers in the game, as far as Crucible goes.
Atomic Breach extends the range of your melee and creates a Void explosion upon impact. The extra range can be nice, but this is generally inferior to the other two melee abilities.
Dark Matter grants health, melee, grenade, and class ability energy upon landing a Void ability kill. This can help keep all of your abilities good to go pretty consistently if you're efficient with them.
Handheld Supernova allows you to convert your grenade energy into a short-range Void blast on release. This is a one-shot melee ability, making the Attunement of Fission viable in Crucible, despite the lackluster super.
3 ATTUNEMENT OF CHAOS
Attunement of Chaos has the abilities: Entropic Pull, Chaos Accelerant, Cataclysm, and Bloom. Entropic Pull drains your enemy's life force and uses it to recharge your grenade. This can be nice for builds that rely on heavy grenade use, which can be effective given the next ability.
Chaos Accelerant allows you to overcharge your grenade, making it deadlier. This can be very nice, especially with Axion Bolt and Scatter Grenade that have a higher likelihood to hit.
Cataclysm makes the Nova Bomb travel slower and seek enemies. The Nova Bomb will detonate into smaller seekers, as well, and you can fire your weapon into the Nova Bomb to detonate it early. As far as Crucible goes, this mostly just gives enemies more time to get out of range of the Nova Bomb, or at least kill you and get a trade.
Bloom makes enemies killed by your Void abilities explode, which can be nice when enemies are grouped close together.
2 TRANSVERSIVE STEPS
Transversive Steps isn't just a good choice for Voidwalkers; it's a good choice for any Warlock that values high mobility. Plus, sprinting will reload your current weapon after a short time, making it especially easy to stay involved in fights. Not to mention that using Blink accentuates a mobility build, so Voidwalkers, theoretically, can get the most benefit out of this exotic.
1 ABILITIES ARE EVERYTHING
Voidwalkers are built around making heavy use of your ability, instead of buffing your weapons. Each of these Attunements is going to play drastically differently, and because of the kind of lackluster mobility abilities, you're going to have to make heavy use of the Attunement abilities to not be at a disadvantage to other Guardians.
