Topic says it.

I've never really used any ground based targeting spells. Not even sure what the terminology is for doing this or searching for tips. I know ISBoxer has repeater regions which i use for healing. Would I set up something similar?

I'm currently wanting to get set up for healing rain as well as earthquake for my Shaman
Priest power word barrier spell seems a handy one as well.

Thanks for any tips/links etc.
