Well, that's definitely one highlight of Alice, being able to debuff various stats (offensive and defensive ones). Some of her attacks have "strange" formulas, meaning that they can deal rather large amounts of damage, or deal something close to 0 depending on what enemy you use the attack on. Overall, I would say that she's a mixed bag of goodies capable of covering a lot of tasks, but isn't the best at doing them. With this she's good as a "support" unit of sorts (stacking debuffs for instance) or for dealing random encounters; her large SP growth should also mean that she can stay out and repeatedly debuff / roll mooks without needing to get switched out (later of course, when the SP increases per level up actually become notable). Possibly also filling the role of an attacker during boss fights while you switch your glass cannons out to recharge / prevent them from dying to a boss attack. Her stats are fairly well-rounded and she levels up rather quickly as well, meaning that her stats actually do keep up to a certain point (don't overdo it).
