How to run multiple auras as ES phy wander?

I want to play a ES based physical power siphon witch build. But I'm slightly confused to how those people are able to run multiple auras if they don't even take mana reservation nodes. .__.

To what build do you refer ?

I would think, they use a shavronnes wrapping ? It allows them to reserve aura on life too, without beeing afraid in chaos damage. (Its one of the most expensiv items in the game!)

My scion wander in dom ran hatred/disc on mana no problem. Power siphon is a very expensive attack so you're going to need a big mana pool to get your leech rate high enough anyway, so if you get 15-20% reduced mana reserved from the tree 2 60% auras should be easy. But you need 250+ mana free to run siphon, so it will be hard to do more than that w/o heavily investing in aura nodes.

A bigger worry to running a wander now would be the leech & VP changes, I'm not convinced you'll be able to leech enough life (or mana) w/o top end gear
