Help with priest macro please

Is there a possible macro that can cast purge the wicked normally and switch to shadow word: death when the enemy target drops below 20% health? Any help would be greatly appreciated. Thanks.

Nope

You can change which spell you’re casting using a modifier.

#showtooltip
/cast [mod:alt] Shadow Word: Death; Shadow Word: Pain

OK, thanks :+1:

Wouldn’t you be able to simply:

/cast Shadow Word: Death
/cast Shadow Word: Pain
if the abilities share a GCD then you would always cast SWP unless you can use SWD.

No. Read the previously quoted pin.
