Pirate Coast - 1

Strategy
Choose Red in Samurai, Matilda in Druid and Bomb in Pirate/The Blues in Tricksters. Attack with the birds every turn, and then, if the Birds' health is not full, then use Matilda's secondary skill. Take down the Big Pirate and then the Ship's Kobold. Give the Rage Chili to Red when it is full. Repeat this over until you win or lose.

In Summary
Big Pirate is immune to harmful effects, so it would be best to use simple attacks.
