I focused on agility and will when I tried Anjali in the demo. But you can really develop her like you want. Want to use her melee form? Armor, attack and retribution works well. Her fire form I only used to spam abilities. Agility, momentum and will. But you don't have to stick to one type of equipment for your character. I have a lot of items for the same item slots, IE two spears, two helmets etc, because they have different bonuses that work well for different situations.
