Collins’s shop
Collins sells the Collector for 100,000,000 Penya. Batteries power it: a Regular Battery costs 1,500,000 Penya and lasts 30 minutes, a Silver Battery costs 250,000,000 Penya and lasts 10 days, and a Gold Battery costs 500,000,000 Penya and lasts 20 days.
Silver and Gold Battery durations count real-world days, not online time.
Collecting
Some collection attempts come back empty; that is part of the system, not an error. A successful collection shows the item and quantity you received.
Collection pieces and exchanges
Collection rewards include pieces for Ascension materials, Mythic Cards, Shards and Red Chip Boxes, alongside Sunstone, Moonstone and Lucky Cloud pieces. Collins handles their exchanges; check his exchange list for each recipe.
