FlashoverPassive

EradicationPassive

Soul Fire4 sec cast

The very first talent row for destruction already throws up many questions to the player about just how you want to do damage. Flashover and Eradication can both have their moments to shine and will be your main choices.

Flashover - This talent is generally always the best option when playing a destruction warlock. It makes the spec much smoother to play giving you that extra backdraft charge on top of giving you synergy with Cinders.

Eradication - Now, this talent is very strong but only under the right circumstances. It can sim higher on single target and 2 targets, but the reason you might not want to pick this talent is because it’s very heavily punished by moment/low haste, and it does not scale anywhere near as good as flashover past 2 targets.

This talent is very strong for short burst windows where you might want to pop 3 chaos bolts as fast as possible. So if you think you can effectively “get away” with picking this talent, then on paper it should be better for most single target and 2 target encounters, just know Flashover is the safer and easier pick.

Reverse EntropyPassive

Internal CombustionPassive

ShadowburnInstant

Reverse Entropy - Yet again this talent is pretty much the always go-to talent no matter what type of gameplay you’re doing. The proc rate is quite good and is the only real viable option in this section.

Internal Combustion - Very single target focused talent, and you would need lots of haste to make this work. It does sim slightly higher than RE.

Demon SkinPassive

Burning RushInstant

Dark PactInstant

You can use either Demon Skin, Burning Rush or Dark Pact. All 3 are viable for different situations.

Demon Skin is great if you’re stacking up a lot and taking constant damage with not much movement in the fight.

Burning Rush is great when there is a lot of movement and you need to help with mechanics or dodging certain mechanics. 

Dark Pact is a great option when you need to soak heavy damage, however you need to make sure you use this ability when you’re full health to get the full effects as the damage absorbed is based on current health.

InfernoPassive

Fire and BrimstonePassive

Cataclysm2 sec cast

Cataclysm - Cataclysm sims the highest with anything from around 1-4 targets. This option just helps with spreading Immolate on all targets and deals a large burst of AoE on impact. In this talent section, all 3 have their own good niches, however I always prefer Cataclysm in every piece of content I play.

DarkfuryPassive

Mortal CoilInstant

Howl of TerrorInstant

Mortal Coil - Pretty much the only choice you want to choose in raiding for the burst heal on demand. Havoc + coil for double healing! (only on 2 targets)

Roaring BlazePassive

Rain of ChaosPassive

Grimoire of SacrificeInstant

Roaring Blaze - This talent has become very strong and is pretty much the “go to” single target talent and you will most certainly want to be playing Cinders with this.

Rain of Chaos - VERY strong talent. This talent will pigeonhole all your damage into infernal, but it has some drawback due to the 15% chance RNG on spawning another Infernal. This talent is best paired with Wilfrids.

Soul ConduitPassive

Channel DemonfireChanneled

Dark Soul: InstabilityInstant

Channel Demonfire - Solid option when you want to do good single target damage with some splash AoE. Great synergy when used with Cataclysm so I would always advise to use both of these talents together.

Dark Soul: Instability - Most of the time this is your go-to talent for Single target or 2 targets encounters. For progression raiding, having a powerful cooldown is always really good if you need to nuke an important add down or to do big damage during a burst window.
