[X] Quiet Extraction: You know where Ardan is being held, try to quietly slip in and rescue her without having to fight the whole camp. This will be hard, and it will separate some members of the posse from the rest, but if successful you'll get what you want without a major battle. At least you should be able to make sure Ardan is safe if the fight starts.
[X] Fight cautiously: Artemis told you to keep your power hidden. You will use magic to fight, but you'll try to limit your oddities and keep your wings in check. This will weaken you noticeably.
[X] Fight vigorously: There are a lot of bandits here… you're going to need to try really hard if you want to win. Use your powers to their fullest, no matter who might see.
[X] Fight as a dragon: Forget subtlety, you aren't letting anyone get hurt. Mother told you to be ready to call your dragon. You are under the sky, let her roar. (You are filled with Determination)
[X] Frontal charge: The bandits are on edge, but they don't know you're here yet. A quick strike will still send them into disarray. However, if you don't win in those first minute or so, then the bandits will have numbers on their side and might be able to do serious damage, or even hurt Ardan if they realize she's why you're here.
