Games : How to get 85% max all resist?

I saw a video from Kripparrian where he has a build with 85% max all resist.

But I can't find any real ways of increasing my max resists.

Barbarism only increases max fire resist by 1% and potions only increase max resist temporarily.

Is this something that has been changed recently?

Edit:

Purity of elements gives no extra max resist

On the resistances page says indeed that there are ways to increase max resistances.

But there's no real way of increasing them to a permanent 85% percent, they all have problems:

• Saffell's Frame Increase all max resist by 4%, but does not block normal attacks


• Divination Distillate Increases all max resist by 6%, but only for 5 seconds


• The aura's each only increase max resist of one type by 5%.
