Daisy Jane has some healing abilities in her Cleric form, but they're all extremely low tier and seem to have been gathered just to give her a level of plausible deniability regarding her powers. Her Diabolist form however has an extremely varied number of abilities, most prominently focused on on bloody red tendrils, fields of white ice, and exploding miniature stars she flings at her enemies, in addition to more standard diabolist abilities such as demon summoning, hellfire creation, and cursing. Being of the Serpent Diabolist class route however, she has a special focus on Dread Worms, horrible little black inky worm things which she can use to control people, which she uses to control her grandfather's corpse and force her elder brother to protect her once the secret's been lifted. She specifically uses a negative trait that makes them able to be broken free from if a person has a strong enough will, which she chose not only to get points to spend on skills, stats, and positive traits, but because it suited her worldview better. She can use her dread worms to empower herself as well, being able to control body parts that have lost functionality due to damage or negative status effects in order to keep fighting, and they are the central focus of her unique Limit - Home of the Brave - which she named after Mobaha's Land of the Free unique limit - which has her absorb all her dread worms into herself and convert all her magic stats into pure strength, agility, and constitution stats whenever her magic ability is hampered or limited, turning her into a close combat power house so that even when locked and shackled by the powers of others, she is still 'free.' This is memorably used when [PROTAG] traps her in Card Castle Null, which disables spells, allowing their final battle to be decided by might and might alone. Like all Americans, she has high constitution by default in order to compensate for lack of enhanced clothing and armor, making her tough even when her Limit is inactive.
