I use smite spec for my Priest 4 Blood DK team. It's pretty nice in heroic and I use it in BH25 man with my guild. This is a two step macro.


Step One - Main DPS Spam Button - I have it click my Right Button 10 which is the third square from the bottom on the first bar on your right side of the screen.

/stopmacro [channeling]
/click MultiBarRightButton10
/castsequence [target=targettarget] prayer of mending
/cast power infusion
/use 13
/use 14
/use 16

Multibar Right Button Macro - You can put a # on the holy fire if you want. I use it in 5 mans because of the Glyph of Smite which does 20% more damage to targets inflicted with holy fire. I disable this in BH25.

/stopmacro [channeling]
/cast holy fire
/cast archangel


Step Two - This is setup so I can cast a hymn without interruption from spamming my dps button.

/stopmacro [channeling]
/cast smite
