Why this build
How the build works
This Enhancement Shaman build has the highest community agreement of any shaman build. Thundering Strikes gives you 5% crit with every spell and attack, and Flurry turns each melee crit into 25% faster attacks for your next 3 swings. More crit means more Flurry, so the two are the backbone of the build.
Mental Dexterity converts 100% of your Intellect into Attack Power. That makes Intellect gear useful for both your mana and your damage, and it is the prerequisite for Flurry. Elemental Weapons improves every weapon imbue: 20% more Attack Power from Rockbiter, 40% more from Windfury Weapon and 15% more Flametongue and Frostbrand damage.
Stormstrike comes in at 15 points, which is level 25 in this order. It strikes for normal weapon damage on an 8-second cooldown and makes your next Lightning Bolt, Chain Lightning or Earth Shock on the target 20% stronger. Shamanistic Focus makes your Shocks and Lightning Shield 45% cheaper, so you can afford to shock after every Stormstrike. Improved Ghost Wolf makes Ghost Wolf instant and usable indoors.
Leveling tips
Take Improved Ghost Wolf before level 20, when you learn Ghost Wolf, so the instant cast is ready immediately. Use a two-hander (or a one-hander and shield) with Rockbiter until 30, then a slow two-hander with Windfury Weapon. Take Stormstrike the moment row 4 opens at 25.
The level-30 Call of Air quest offers an Enhancement weapon. In dungeons, Magma Totem and Fire Nova add AoE. Stay in the melee group so your totems cover the right players.
Changes in WoW Forever
Stormstrike moved up to row 4 with an 8-second cooldown. Mental Dexterity, Shamanistic Focus, Improved Stormstrike, Maelstrom Weapon and the Rage of the Farseer capstone are new. Totems in WoW Forever cover the whole raid, and the totem global cooldown is 1 second. Talent text here comes from client build 70630 without later hotfixes; our research cross-checked it against a hotfixed calculator, so the numbers should be close.
Toward level 60
The most-planned endgame build is 18/33/0: Improved Stormstrike, Mental Quickness, Maelstrom Weapon 5, Spirit Weapons and Rage of the Farseer, with Concussion, Call of Flame and Reverberation from Elemental. Only one site has data so far and guides plan to publish theirs at launch, so treat it as provisional.
