What are you guys doing for bottle caps?

[Idle]

If your getting bad luck with isle aphun try the shard hunting path. You get about 2-3 shards of one colour per trip and do 2 trips a day. Theres a guy inside the Festival PLaza that will take 30 shards of 1 colour for a bottle cap. Thats how im doing it. Takes around a week to get 30 shards but when you do it you get 4 bottle caps from the 4 different colours. Its the best method without relying on luck. Hope this helps!!

I'm breeding for bottle caps. Doesn't take as long as actually getting bottle caps and it's more permanent.

if you get a 30+ winstreak in battle tree every day you'll get 1 bottle cap ez pz
