WotLK Classic Destruction Warlock Spec, Builds, Talents, and Glyphs

Warlocks are pretty straightforward when it comes to talents. You want everything with fire damage and anything that buffs you or your Summon Imp. Talents like Soul Link and Fel Domination can be considered flex points and should be used for Suppression if you need hit.

• Bane
  • This talent reduces the cast time of you two of your main abilities, Immolate and Chaos Bolt
• Aftermath
  • Increases the damage of your Immolate and dazes the target. Largely taken for the damage portion as the daze does not do anything to bosses, but can be nice on the trash packs.
• Demonic Power, Improved Imp, and Empowered Imp
  • All three of these talents synergize and attribute to why your Summon Imp does so much damage. Plus, thanks to Empowered Imp, whenever your Imp crits, your next ability crits as well.
• Improved Immolate
  • This talent, mixed with Aftermath and Glyph of Imp, makes your Immolate do very high of damage.
• Emberstorm
  • Increases the damage of your Fire spells by 15% and reduces the cast time of your main ability, Incinerate.
• Conflagrate
  • One of the main abilities of Destruction. This spell consumes your Immolate or Shadowflame and does 60% in instant damage to the same target. Glyph of Conflagratecan be used to avoid consumption of Immolate and Shadowflame.
• Shadowfury
  • This is an instant cast AoE ability that stuns everything it hits. It is to be used on cooldown during AoE.
• Backdraft
  • The main talent of Destruction. Whenever you cast a Conflagrate, the cast time and global cooldown of your next three Destruction spells is reduced by 30%. A lovely spell and integral to the rotation.
• Chaos Bolt
  • Sends a bolt of chaotic fire at the enemy, dealing high damage on a 12-second cooldown. This bolt ignores all absorption effects and cannot be resisted.

Glyphs are a new consumable of sorts introduced in Wrath of the Lich King. Glyphs greatly improve certain spells when you learn them, supporting and even enabling some builds. Glyphs are not permanently learned, so you will want to carry multiple glyphs on you so you can change them quickly depending on the raid or boss encounter you are in. Destruction has some really powerful Glyphs that make the gameplay a little more fun.

1. Glyph of Life Tap — Whenever you Life Tap, you gain 20% of your Spirit as Spell Power for 40 seconds. This is very important and you must keep this buff on you at all times.
2. Glyph of Conflagrate — Very important. This makes it so when you Conflagrate it won't consume your Immolate from the target.
3. Glyph of Imp — This increases your Imps Firebolt damage by an additional 20%. This mixed with your other Imp talents make your Imp do very high damage.
4. Glyph of Immolate — This is a good alternative to Glyph of Imp and it excels with multi-dotting, since Immolate deals a high amount of damage. It's up to personal preference for which one you want to use.

1. Glyph of Drain Soul — This gives you a chance at an additional Soul Shard when you Drain Soul.
2. Glyph of Unending Breath — This gives everyone with your Unending Breath 20% swim speed.
3. Glyph of Souls — This reduces the Mana cost of your Ritual of Souls.
