I'm trying to make it where, if I'm channeling Penance, it won't get interrupted if I cast GH. I have IF macro'd to cast whenever it is available before casting GH.
I'm not entirely sure what the purpose of the first macro is, as I've never actually encountered a /stopmacro in the wild. But if you're looking to do what Aliahna guessed that macro is spot on.
stop casting allows you to spam heals without breaking penance if you're using it. The macro works with, say, heal and fheal, but not with the spells I have macro'd to run IF. I am not trying to do what Aliahna said.
I'm pretty sure Penance can be clipped.. And ty, for some reason that worked! Oddly enough... that is what I was trying before I asked for help.. strange.
