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
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.
