This lovely macro is on the toolbar of every one of my 70s. It's your general purpose It-Must-Die-Now attack macro. Spitfire totems for Fathom Lord, Demon Chains for Illhoof, Corrupted Lightning totems for Lynx boss, and the amani totems dropped by ZA trash.

You can keep adding targets to this list. The game will run through the whole list until it finds one that exists. I believe you can stack the spells too, it'll just give you error messages for the ones that don't exist.

/stopcasting
/target spitfire
/target corrupted
/target demon
/target amani protective ward
/attack
/cast fire blast
/cast earth shock
/cast arcane shot

yea, add a /script UIErrorsFrame:Clear() to the end

nice man I'll give that a try for sure.

Cheers
