Alolan Islands

The Alolan Islands are accessable while the weekly Acticity is at least Silver rank(1,500 and above). They feature battles against the 5 Kahunas which belong to the strongest non-scaling opponents. Beating one of them grants a 12.5% to win their reward Pokémon. On Gold rank Activity and above (at least 6,000) the chance reduces to 12% but there is also 4% chance to win a rarer Pokémon.
