Yes, you can equip this before a weapon skill, and also you can equip those before casting a spell for Healing Breath. And for the macro just do /ws "whatever WS u r using" <t> /wait 1 /equip Head "Drachen Armet" /wait 3 /equip Head "Whatever Headpiece u normally wear unless it is Drachen Armet"
Yes and no. There is a macro for switching helms around and still getting the affect of the Drachen Armet. But I'm not sure exactly what the timing is on that. Unless you have both AF helms, it's usually just better to leave the Drachen Armet on....
