Got up to wave 44 of endless last week and thought I would make a guide with all the stuff I picked up along the way. Hope it's of some use to anyone who might be trying for the title.

P.S. I barely do any serious content on my mage these days, so I don't really keep up-to-date with mage stuff. So if you spot anything that needs changing, please let me know!
