TBC mage macro help with blizzard and arcane power.

[Moorea]

Tried that initially. If Arcane Power is on cool down, it won't progress to Blizzard and say "that ability is not ready" or something like that.

Well if you have 2 spells that aren't always available it won't work what you can do is

#showtooltip arcane power
/use 13
/use 14
/cast [mod] arcane power
/cast blizzard

So you see if it's on CD or not; if it isn't you use alt the key and otherwise plain key
