Shackle Undead and focus on target

This macro will first shackle your current target and set that target to be your focus target. This will allow you to reshackle a mob without having to retarget it.

Code:

#showtooltip Shackle Undead
/clearfocus [modifier:alt][target=focus,dead][target=focus,help][target=focus,noexists]
/focus [target=focus,noexists]
/cast [target=focus]Shackle Undead

you might want to add stop casting if you want to have one that will instant shackle. You could ofc also have both

Spammable Mind Flay

This macro will allow you to spam Mind Flay without interrupting the one already channeling.

Code:

#showtooltip Mind Flay
/cast [nochanneling:Mind Flay] Mind Flay

Greater Heal mob's target or friendly target

This macro will cast Greater Heal on your target if your target is friendly; if your target is an enemy, it will cast Greater Heal on your target's target.

Code:

/cast [help][target=targettarget][] Greater Heal

very good macro for healing on bosses like Loot Reaver
