She is Tier SSSSS among the SRs. She can clear the 3 star Bahamut Beast's Den by herself because of her amazing Magic Resistance and the Bio Spell. Team her up with Christmas Vinera and Kitone and you have a well rounded trio of powerhouses.
I maxed-out Murmur and she's very useful compared to other SR units. She prioritize healing during Duel or Guildwar but the best part for her is the Jamming Thrust or Flare (Blackmage) when there's a chance to kill. Use a vision card with +HP% to compensate her the lack of health. I have her 1.4k health if you are curious.
true she has an instant range 5 low cost that cancels activations and does L dmg. kinda weird she's not tier A :/ with nargarok sword i could see her has a replacement for mages at pvp lol... or a mage killer :P IMO
Jaay
I'd say her max stats has her ranked low. But she has high resistance's that even it out somewhat for lack of hp.Her and phoebe are S tier SR's to me. Check others resistances to job related attacks . Her grid unlock that to that along with her res unlock mastery plus mag boost . Lancer with flare. Once u add the res up shes pretty beefy despite the low max stats for SR. Actually about to use her vs mont for an earth unit. Being i don't have aileen.
