How To Improve As Destruction Warlock — Battle for Azeroth (BfA) 8.1.5

1. Utilizing Grimoire of Supremacy

When playing with Grimoire of Supremacy, it is very important to ensure you maximize your Soul Shard expenditure during Summon Infernal. Heading into the cooldown with Soul Shards at the ready will make a big difference in getting the damage boost up and running as early as possible. Grimoire of Supremacy works particularly well in situations where there are non-priority targets surrounding the main target. Fire and Brimstone will provide a ton of extra fuel for your single target damage, and Grimoire of Supremacy can pump you up to extremely powerful levels of single target burst.

2. Not Using Rain of Fire Too Liberally

Rain of Fire is a large Soul Shard investment and shifts your damage profile, from focused burst to distributed AoE. The AoE from Rain of Fire is quite significant, provided that targets will stay within the reticle for most of its duration. Remember that at 5+ targets you should use Rain of Fire rather than a Havoc-empowered Chaos Bolt.

3. Dark Soul Usage

After the opener, your Dark Soul: Instability is unlikely to align with any of your other main cooldowns until the 6-minute mark. Dark Soul should be used roughly on cooldown, although you should delay it for a short time if you will be able to cleave during the duration. If you are playing with Grimoire of Supremacy, you should cast Dark Soul after using Summon Infernal and a few Soul Shard generators.

4. Not Refreshing Immolate for Internal Combustion

When playing with Internal Combustion, many players fail to properly manage their Immolate. You should always keep track of your Immolate, as dumping multiple Chaos Bolts will quickly eat up the duration. Try to refresh Immolate when there are 5 seconds or less remaining.

5. Havoc Preparation

Properly anticipating cleave and putting Havoc to the best possible use can add a lot of damage to your parse. Be sure to lead into Havoc with Soul Shards at the ready. Unless you need to refresh Immolate on the main target, you should apply Immolate before Havoc on the second target. Get right into dumping Chaos Bolts, using Conflagrate charges for quick Soul Shard regeneration.

6. Cataclysm Usage

Cataclysm applies Immolate, and should be used to apply or refresh that debuff whenever possible. It is common for many players to refresh Immolate out of habit, only to cast Cataclysm moments later and refresh again. While this is not a huge optimization, it definitely pays to remember. Remember Cataclysm cast on cooldown offers almost 50% Immolate uptime.
