Don't macro frost strike to your main macro. You won't want to waste killing machine on it.


I'd use this

#Showtooltip Obliterate

/castsequence reset=target Icy Touch, Plague Strike, null
/castsequence [mod:shift]Blood Boil;[mod:alt]Outbreak;Obliterate
/cast !Horn of Winter


Then have frost strike on another macro, one I'd call the dump/burn key.

#Showtooltip Frost Strike

/castsequence [mod:shift]reset=120 Desecrated Ground, <trinket>;[mod:alt]<trinket>;Empower Rune Weapon;Frost Strike

If you are boxing the dk then just switch to unholy. Less proc based.
