Usual team, but Cecilia's build is altered to fit the map.
Jamke has Cancel Affinity. Raventomes still work against Jamke so long you forego using Triangle Adept. Raventome with Bowbreaker does him in, and Distance Defence seal helps mitigating Astra.
On the second turn, I have Cecilia take hits from the flier to avoid the axe knight teleporting with Guidance.
I couldn't clear the map without Bowbreaker, but it was fairly easy once I gave it to Cecilia, my Raventome user.
