For both macros below, the target for your heal when you press the button is determined in the following order:

Yourself, if you are holding the CTRL key when the button is pressed; you will retain your current target
Your current friendly target
The friendly character you’re currently mouse-hovering over (or their portrait-bar)
Your current friendly focus-target
Yourself (if you have no friendly target, focus, or mouseover)
This order of priority makes it easy to quickly choose the appropriate target for healing. Hold CTRL to always heal yourself; target a friendly character to direct heals at him/her; mouseover a character to direct a heal at that character without the need to click first (if you don’t already have a friendly target); and finally, heal your focus-target (handy for keeping the main tank healed while selectively healing other characters on demand).
The following macro is used primarily when being hit in combat. Since Lesser Healing Wave has a 1.5sec cast time you can usually cast it without interruption, unless being hit by many mobs at once.

#showtooltip
/target [modifier:ctrl] player
/cast [exists,nodead,help] [target=mouseover,nodead,help] [target=focus,help] [] Lesser Healing Wave;
/targetlasttarget [modifier:ctrl]

The following macro is dual-purpose: it serves as a big emergency instant-heal when Nature’s Swiftness is ready and you’re in combat (targeting priority order still applies); and, when not in combat or NS is not ready, it works as a stronger, slower heal. This is the preferred macro to use when serving as a healer in instances and parties, as it is more mana-efficient than the previous macro. If you aren’t currently in combat but need to instant-heal a party member, you’ll still want to manually cast NS first.

#showtooltip Healing Wave
/target [modifier:ctrl] player
/cast [combat]Nature’s Swiftness
/stopcasting
/cast [exists,help] [target=mouseover,help,exists] [target=focus,help,exists] [] Healing Wave
/targetlasttarget [modifier:ctrl]

Note in the above macro that unneeded spaces have been removed to fit within the allowed 255-character limit for macros.
Change [modifier:ctrl] to [modifier:alt] or [modifier:shift] if you wish to use a different modifier key for self-directed heals.

/targetfriend [nodead]
/cast [nodead] Lesser Healing Wave(Rank 1)

Note that manually cycling through friendly players and healing only those who are damaged is a more mana- and time-efficient method, but this is simpler. To really maximize the effectiveness of this strategy check out the Healbot addon[[1]].

/targetfriend [nodead]
/cast [nodead] Healing Wave(Rank 1)

Healing Wave (Rank 1) is cheaper than its Lesser counterpart, and is a faster cast for Restoration Shaman. It also applies the Healing Way buff for those who have the talent.

#showtooltip
/cast [stance][combat,nomounted] Ghost Wolf;<mount name>
/dismount [mounted]

to make your macro cast Ghost wolf no matter what when you right click you can add this line. Very useful in WSG

#showtooltip
/cast [stance][combat,nomounted][button:2] Ghost Wolf;<mount name>
/dismount [mounted]

Or even with modifier keys such as alt, ctrl or shift

#showtooltip
/cast [stance][combat,nomounted][button:2][modifier] Ghost Wolf;<mount name>
/dismount [mounted]

Ghost Wolf, Mount and Flying mount in one macro:

#showtooltip
/cast [combat,nomounted][button:2][modifier] Ghost Wolf
/cast [nostance,nocombat,flyable] <flying mount name>
/cast [nostance,nocombat,noflyable] <standard mount name>
/dismount [mounted]
/cancelform [stance]

This macro will mount you on your flying mount if it’s accessible using the new “flyable” option. If it’s not, you will mount your normal one instead. If you are in combat, you shift into Ghost Wolf instead. If you right-click the macro button or keep a modifier (alt, ctrl, shift, option)pressed while you use the hotkey you will shift into Ghost Wolf regardless of the situation. Use the macro again and you will dismount/shiftshape back. (As of Patch 2.3.0, /cast Ghost Wolf will not unshift out of Ghost Wolf, so you need to use /cancelform instead)

The indoor part of the last macro is just for graphic purposes, to show the flying mount icon indoors, feel free to change that, in any case no one of the three actions will work in doors.

/cast [combat,harm] Nature’s Swiftness
/stopcasting
/cast [harm] Chain Lightning

The [combat] modifier allows you to avoid “wasting” Nature’s Swiftness when out of combat.
This macro will function similarly to the above one, except that it will also activate your trinkets and use Elemental Mastery. You’ll need to be targeting someone/something that you can cast Chain Lightning on for this macro to work. Substitute Lightning Bolt for Chain Lightning if you would rather the macro cast Lightning Bolt.

/stopmacro [nocombat,noharm]
/use 13
/stopcasting
/use 14
/stopcasting
/cast Elemental Mastery
/stopcasting
/cast Nature’s Swiftness
/stopcasting
/cast Chain Lightning

[edit] Cure poison/disease

This will cast Cure Poison on the character that the mouse is pointing at. Works on raid windows as well, and CT Raid Assist will highlight poisoned raid members with a green background.

/cast [target=mouseover,exists] Cure Poison

The below macro has many fallbacks to cover what happens if you’re not mousing over a target. In order, it tries to cure your mouseover target first, then it attempts to cure your target if they’re friendly, then the target of your target if they’re friendly, then finally yourself.

/cast [target=mouseover,help,exists] [target=help,exists] [target=targettarget,help,exists] [target=player] Cure Disease

Both of these macros work for Cure Disease and Cure Poison.

/cast Nature’s Swiftness
/stopcasting
/cast Healing Wave

Assuming you have two healing trinkets with a “use” function, this will use them both, interrupt whatever spell you’re casting at the moment, and instant cast Healing Wave. If you’re not in combat, the macro will not waste your trinkets or Nature’s Swiftness and simply cast Healing Wave.

#showtooltip Healing Wave
/cast Healing Wave [nocombat]
/stopmacro [nocombat]
/stopcasting
/use 13
/stopcasting
/use 14
/stopcasting
/cast Nature’s Swiftness
/stopcasting
/cast Healing Wave

/cast [target=player] Lesser Healing Wave
/cast [target=player] Healing Wave

/castsequence reset=6 Searing Totem, Mana Spring Totem, Grounding Totem, Strength of Earth Totem

#showtooltip
/cast Stormstrike
/startattack

/castsequence reset=7 Windfury Totem, Grace of Air Totem, Stormstrike

keep SS separate to time it with the WF cooldown if you wish.

Clear your focus if your old focus target is dead
Clear your focus if your old focus target doesn’t exist anymore
Set your focus on what you have targeted if you don’t have a focus already
Place a Star marker over the head of the focus target (if you are group/raid leader/assistant)
Earth Shock the Focus target
If you are grouped, announce the Earth Shock to the group.

This allows one button to do the whole Earth Shocking process without the need for a separate /clearfocus button (though an additional macro that does a /script SetRaidTarget(“focus”,0) and then a /clearfocus would be useful to let the group know the interupt is free game now might be useful)

/clearfocus [target=focus,dead]
/focus [target=focus,noexists]
/script SetRaidTarget(“focus”, 1)
/cast [target=focus]Earth Shock (Rank 1)
/stopmacro [nogroup]
/p –== Shocking and Marking “%T” ==–

As of 2.1, you can also use %f to insert your focus name in chat just like %t inserts your target. Thus, to alert your party that you are interrupting (or re-interrupting) your focus and not your target, try this instead of the last line above:

/p –== Shocking and Marking “%f” ==–
