Shaman builds

For solo questing to 60 with a two-handed weapon. You fight in melee with a weapon imbue, use Stormstrike and shocks, and spend Maelstrom stacks on fast or instant Lightning Bolts to heal or finish targets. Improved Ghost Wolf early makes travel between quests much faster.

• Improved Ghost Wolf makes Ghost Wolf faster to cast and usable indoors, worth taking before level 20.
• Mental Dexterity turns Intellect into Attack Power and opens Flurry, so Ancestral Knowledge feeds both mana and damage.
• Stormstrike hits for weapon damage and buffs your next Lightning Bolt, Chain Lightning or Earth Shock; Improved Stormstrike can add mana regen while casting.
• Maelstrom Weapon stacks from melee hits and shortens and cheapens your next Lightning Bolt.
• Shamanistic Focus lowers the cost of shocks and Lightning Shield, and Elemental Devastation turns spell crits into melee crit.

For a caster Shaman in raids and dungeons. You keep Flame Shock up, cast Lava Burst on cooldown and fill with Lightning Bolt, using Chain Lightning on groups. The Restoration and Enhancement points go to mana and crit, since mana is the spec's main limit.

• Lava Burst does extra damage when your Flame Shock is on the target, and Call of Flame boosts both and extends Flame Shock.
• Elemental Alacrity shortens Lightning Bolt, Chain Lightning and Lava Burst casts and opens Lightning Overload, which can cast a free half-damage copy of a bolt.
• Elemental Fury raises the crit damage bonus of your Fire, Frost and Nature spells, helped by Thundering Strikes crit.
• Mindfulness and Water Shield from Restoration plus Convection, Elemental Focus and Tidal Focus are there for mana.
• Elemental Mastery at the bottom shortens Lightning Bolt and Lava Burst casts for 15 seconds as a burst window.

Blizzard's deep dive said Elemental Mastery was removed and Lava Burst was the 31-point talent, but the launch client data has Lava Burst on row 5 and Elemental Mastery on row 7, and this preset follows the client.

For melee Shaman in raids with a two-handed weapon. You keep the imbue and party totems up, Stormstrike on cooldown, shock when it is ready and turn full Maelstrom stacks into Lightning Bolts. Rage of the Farseer is your personal attack speed cooldown.

• Rage of the Farseer gives a large attack speed boost on a cooldown and requires Mental Quickness.
• Maelstrom Weapon lets you weave fast or instant Lightning Bolts between swings, and Stormstrike buffs the next one.
• Mental Dexterity, Flurry and Elemental Weapons build the melee core; Ancestral Knowledge raises Intellect, which Mental Dexterity turns into Attack Power.
• Spirit Weapons cuts your threat while you are not using Rockbiter Weapon.
• Elemental Devastation, Concussion, Reverberation and Call of Flame add spell crit transfer, shock damage and uptime, and stronger Flame Shock and Fire totems.

For raid and dungeon healing. You keep Riptide on the tank or whoever drops, use Chain Heal on groups and Healing Wave for big single-target heals, and run mana and healing totems. The rest of the tree is built around mana: Mindfulness, Water Shield and Mana Tide Totem.

• Riptide is an instant heal plus a heal over time, and it makes your Chain Heal stronger on that target. It requires Healing Way, which boosts Healing Wave.
• Water Shield returns mana when you are hit or when your heals crit, which pairs with Tidal Mastery and Thundering Strikes.
• Mindfulness keeps part of your mana regen going while casting, and Mana Tide Totem restores mana to your group.
• Nature's Swiftness makes one Healing Wave instant for emergencies, and Ancestral Healing raises the target's armor after a heal crit.
• Purification raises all healing, Restorative Totems strengthen Mana Spring and Healing Stream, and Improved Ghost Wolf makes repositioning quicker.
