Hysteria Macro

/cast [target=focus, help, nodead][target=player] Hysteria
/stopmacro [target=focus, nohelp][target=focus, dead]
/script SendChatMessage(”You have Hysteria, damage increased by 20% for 30 seconds”, “WHISPER”, “Common”, UnitName(”focus”));

that should do exactly what you want, and it wont screw up if you have a weird focus.
