So, I got Deirdre as my free summon from the BHB banner, +Spd/-Atk. I'm happy I got her, since I certainly can use more green mages and she's only my third unit who's effective against dragons. I'm just not sure what to use as her A skill. Should I focus on boosting her speed or improving her attack ? I'm not sure if it's worth it to compromise her magical bulk in order to boost both.
I would say give her Swift Sparrow if you have it, 31 Spd isn't going to be enough to double most units, LnD is a good alternative though, IF you want a Player phase Deirdre, otherwise Mirror and Fierce Stance are good A slots to use as a mage tank in enemy phase.
SS could be Spd+3 for player and Distant Defence for Enemy phase.
Death Blow would best be used to handle Blue Dragons.
Unless you want to use her for endurance modes like Chain Challenges, Fury seems perfect, despite her lack of a large HP pool. It covers Atk, Spd, Def, and Res. In single maps, you will barely notice the HP penalty, unless there are somehow like 3 mages you want her to bait I guess. Anyways, Fury looks to be just what you need, and if not, go with Death Blow to improve Atk.
