Heavy Destruction Heavy Destruction is a warlock talent build . Advantages . The advantage of this build is a very high DPS and some very big critical hits . It is one of the best PvP focused builds available . Devastation , Improved Searing Pain , Ruin , and Emberstorm will mean very very big critical hits , and critical hits will be much more frequent when Devastation is working with Improved Searing Pain . Improved Immolate and Conflagrate will be your main tools for damage , and Shadowburn is your death strike when your opponents health is in the red . Intensity makes your Rain of Fire and Hellfire abilities castable without interruption , which is frequent without the talent ( Hellfire is very useful in BG ' s when 8 or 9 enemies can be attacked at one time , and you can sacrifice your self for the greater good , and you can soulstone once dead ) . There are talents that should be avoided in the destruction tree , however , those being Pyroclasm , Cataclysm , and Aftermath . Everything else is up to you . The two best PvP pets also get quite a buff with this build . Many people sink 1 point into Improved Firebolt and 3 / 3 in Improved Imp , providing more damage in less time ( and a very powerful Blood Pact to boot ) . Improved Lash of Pain will really add to your Succubus ' s DPS , and will be cast almost constantly when she isn ' t busy seducing her targets ( and she also manages to eat her mana in a few seconds ) . Both these abilities will make a human opponent put priority on killing your pet instead of you , giving you time for DoT ' s , Shadow Bolts , and Conflag . Typically the only non - destruction talents taken are Improved Corruption , Improved Imp , Improved Life Tap , and Demonic Embrace . This build IS flaming temporal doom . Disadvantages . You eat mana . Life Tap exists , but if you keep casting Hellfire , you will run dry ( you can still easily outlast a mage , however ) . This build also focuses on fire damage , and a lot of mobs have high fire resistance , but the same can be said of any type of spell . Shadow Bolt is going to take a long time to cast , since you don ' t have Nightfall , but it won ' t be that much of a problem if you aren ' t used to Shadow Trance already . This build also offers nothing for defense , and some abilities buffed in this build will drastically cut down on your time spent alive ( Hellfire ) . It also lacks in PvE when compared to other Warlock builds ( Dark Pact and Soul Link builds come to mind ) . This build also does not offer much until you are high enough in level to get Ruin , so people tend to respec into this after Level 35 ( which gives Improved Corruption in addition to Ruin ) rather than sinking points into it right away . But , in the end , if you are playing on a PvP server , it won ' t get much better than this . One Nuke . One Nuke is all about needing only one nuke to defeat an opponent . Any warlock that expects to take on all classes with a high chance of success is going to have to use fear / charm sooner or later . All classes have counters to these spells , but it is rare for diminishing returns to be exhausted by counters alone . Soulfire is a big part of this build . Quite often for a well geared warlock the Shadow Bolt - > Immolate - > dot - > whatever - > Conflagrate - > Shadowburn combo will be enough to defeat an opponent . This is the secondary combo in the One Nuke arsenal . Substitute maxed out Soulfire for Shadow Bolt and you have a nuke that rarely leaves an opponent alive . Pyroclasm and Aftermath come together to make this nuke absolutely devastating . Sometimes nothing will proc and there won ' t be any crits ; in this case the damage will still make things difficult for whoever is on the receiving end . With a reasonable crit chance the probability of no procs and no crits is very low ( about 31 % assuming a 15 % chance to crit ) . This means that in most cases the target will , in addition to taking heavy damage : be slowed by 50 % ( virtual - death against rogues ) , and / or be stunned for 3 seconds ( virtual - death against nearly everything ) , and / or die instantly . This form of burst damage allows the warlock to win battles against 2 opponents ( or more depending on their teamwork ) as one target can be killed before fear / charm wears off on the other . Destruction Must haves : Bane 5 / 5 Destructive Reach 2 / 2 Devastation 5 / 5 Shadowburn 1 / 1 Ruin 1 / 1 Improved Immolate 5 / 5 Conflagrate 1 / 1 Highly Recomended : Emberstorm 5 / 5 Aftermath 5 / 5 Intensity 2 / 2 Pyroclasm 2 / 2 Improved Shadow Bolt 5 / 5 * Special mention : Improved Searing Pain 5 / 5 Improved Searing Pain is a much maligned talent . A warlock with this many talent points in destruction is going to have a reasonably high chance to crit . Assuming a modest 15 % chance , this talent doesn ' t even double the crit chance of Searing Pain . This is significant because , even with Emberstorm , two Searing Pain crits will not do as much damage as a single Shadow Bolt crit - - and after Bane the former takes longer to cast ! The fact of the matter is that this talent will almost never increase damage on either end of the spectrum ( average < - - > burst ) . Affliction Must have : Improved Corruption 5 / 5 Highly Recommended : Suppression 3 / 5 Improved Corruption is useful in pretty much all situations , but can be the difference between life and death against certain classes . A rogue can vanish out of Curse of Agony and make the warlock pay for an incomplete nuke . A druid can dispel Curse of Agony , run away , heal , stealth , and come back with a vengeance . Improved Corruption can be used prevent these scenarios . Suppression reduces the chances of the warlock ' s opponent resisting curses , and more importantly , Fear . Demonology Must have : Demonic Embrace 5 / 5 Every little bit of health ( and mana ) can help in close and / or extended battles . Professions As this is a PvP build , you should strongly consider either Herbalism + Alchemy or Mining + Engineering , since the crafting professions are next to useless in PvP .
