Rare Fighter Rush

Rare Fighter Rush is a series of short-lived easy islands allowing an easy recruit of certain characters that are usually low-chance, 'secret', fortnight characters.

Event dates:
 * July 11-26 2017

Notes:
 * gem awarded upon clearing each mini-island for the 1st time
 * each island requires 14 stamina
 * boss drop rate estimate at about 50%
 * high drop rate of cola

During the first occurrence in 2017, the event consisted of five mini-islands, each available for 4 days:
 * Rare Fighter Rush! The Maiden Awakens - featuring Sanji Candy
 * Rare Fighter Rush! The Young Warrior - featuring Aisa
 * Rare Fighter Rush! Hurricane - featuring Dog Penguin
 * Rare Fighter Rush! Blade Man - featuring Daz Bones, Convict Mr. 1
 * Rare Fighter Rush! Heso! - featuring Conis

How to beat: those islands are very easy, closer to 5-10 stamina fortnights, featuring a lot of boosters and evolvers. Recommended to use Baccarat, Haruta or Legend Buggy for increased drop rates.

Farming notes: Only Dog Penguin has some limited use due to his good special. Aisa and Daz Bones are very niche with very limited uses. Sanji is useless (but can be used as sockets for better Sanjis). Conis is just trash all round.
