Mental Barrier

Mental Barrier is the fourth skill in 's Reticence skill branch. It reduces the damage she takes by 25% from ether attacks with an area of effect. This is defined as any ether attack with a range that is not "single opponent".

Overview
This skill mostly helps protect Melia from being whupped without getting a vision for it because she doesn't have the aggro directly, which is all the more likely for her because she has the lowest HP. This doesn't mean she should feel welcome to stand around in range of such attacks, but it helps. It's probably the most difficult skill to link in the entire game - only half the party can get a square from Melia, they all need high affinity to do it, and it has the second most expensive coin cost.
