With update R25 also two rarer variants of Keepas with more/better loot have been added to the game: Golden Keepa (even rarer than blue and silver Keepas) Keepas can drop a range of many different items when killed or harvested as Pets, but they will always give away at least 1 Arcstone. (While Golden Keepas can drop up to ca. 50 Arcstones at max.) If you kill ordinary blue Keepas, their Loot Bags will usually contain Coal, Gunpowder, Moss Torches, and/or Extractors, perhaps a Wood Sword or a Wood Mining Cell occasionally, and only very rarely a Note, Data Chip or a rare Recipe.
