I'm at what I'm pretty sure is the final battle of Costume Quest but it seems impossible, for a number of reasons:
- I'm up against 2 bosses simultaneously, with 4000 HP each.
- Araxia can apparently decide to become invulnerable for several turns.
- While Araxia merely hits hard, Big Bones hits like a truck, bringing the entire party down to critical levels in one attack.
- Taking Big Bones out first doesn't seem to be possible because he can't be harmed, not even with area effects.
How do I beat this thing?
