Blanc, as always, is a tank first and foremost. She has the highest defenses of all characters, innately increases her magic resistance, has access to defensive buffs, and has access to HDD, heightening her stats for more defense or to increase her attack power and put her into a more offensive role. Offensively, Blanc is alright. With the power of HDD, she'll be doing more damage than the non-CPUs, but her strength won't reach the power of any of the other CPUs or even the Candidates. That being said, the damage she does do is respectable, though her stronger attacks tend to use less hits, causing them to hit the damage cap fairly early. Something to note, is that Blanc has a distinct affinity for Ice elemental attacks, even having some EXE Drives with her sisters of the same element. Blanc won't be too useful for fighting groups of enemies, though her EXE Drive has a great AoE range for wiping out enemies and increasing the gauge will be easy since Blanc has early access to a 7 hit rush combo and the Super EXE Gauge plan makes things significantly easier. Where Blanc does excel is in boss fights, where she'll be able to take the most hits and revive the party should it come to that. Her defensive buffs, one for physical and magical attacks each, are insanely useful for the party's longevity. Also, her strength buff is far more useful than Neptune's or Noire's since it also increases defense. With a health regen chip, Blanc can easily survive a boss encounter with nearly no external healing. Though, alternatively, an SP regen chip could be just as useful in order to constantly use Blanc's defensive buffs.
