The best part for me when playing as Zeus is the "Relic of Asclepius" imo.
This as it constantly gives you +9 magic/sec when your health drops below 20!
And as most of you know, people go ape sh:it when the see someone with low health.
Making them uber predictable, and there you are, whit a pretty much unlimited replenishing source of magic!
Just changed to this yesterday to try it out and it really does give the most magic. Thanks man!!!
