Reny

*Her Healing Skills themselves are almost better than Elle, but she's worse because her crit rate is only 10%. However, she can be fantasy-ed, which makes her a great choice for a healer.
*Moreover, a little birdy told me she will be one of the first to get lvl6 skills.
*She also has a -20% Matk DMG Received buff for the whole party. It's as good as Celenia's, but doesn't have the HP buff. And remember, this buff can be stacked with Eline's -25% incoming magic dmg reduction and Nohara's buff that reduces everyone's MATK(friend and foe) by 50%.
