Ether Def Up

Ether Def Up is a gem effect in Xenoblade Chronicles and Future Connected. It raises the user's ether defence.

Overview
There are two ways to go about defensive gems: give them to softer characters so they can take a few more hits, or give them to tanks so they can take a lot more hits. Which one to go for is largely a matter of taste, assuming that the enemies nearby actually have attacks. Of note is that, being a dodge tank, is most likely to appreciate having extra protection from specifically ether attacks.
