Migraine, capping

I was just wondering, if there anywhere in Hardmode I can cap Migraine, because it's to mucha pain to cap at ring of fire...

Both wikis say you can only get it at RoF. I say wait a bit till elite mesmer tomes drop to 5-8k then get it through that method.

Its easy, its just outside the gate, you don't need the tome.
