If you are a NightElf, you can use this macro to work like a second vanish. It only works if Shadowmeld is not on cooldown, and you can get knocked out of stealth if your Cloak of Shadows is on cooldown. Leave the spell icon as a ? because it will show the icon and cooldown for Shadowmeld (most important part of spell).
- Code:
#show Shadowmeld
/cast Cloak of Shadows
/cast Shadowmeld
/cast Stealth
This macro will remove DoTs with your Cloak, then Shadowmeld you (so you have to stop moving to use it) and then stealth you. Once you look at your buffs and see Stealth (should be instant but isn't always...) you can run around.
Use this as a last minute effort to get away from a mob or to exit combat in raids or single player.
Shadowmeld has a 2m CD and Cloak of Shadows has a 1.5m CD; Vanish is a 3m CD. So you can do Vanish, then later do Shadowmeld/Vanish macro, and both will come off cooldown around the same time. This only works for Night Elves of course.
