Zephyr reduces AoE damage taken by 20% and increases movement speed by 30% for the evoker plus the 4 nearest allies within 20 yards, for 8 seconds.

Because the buff is unique, multiple evokers casting Zephyr on overlapping targets will overwrite each other rather than stack. It only mitigates damage that area-of-effect avoidance applies to.

Slot it onto a specific AoE damage event where DR for a small group is valuable, effectively treating it as a mini group-wide cooldown.

It costs a global cooldown for the evoker, so avoid lining it up with windows where they need to be casting heals or empowers.
