Daily Pet Fusion

Every day, you have 24 bonus pet fusions. These bonus pet fusions will give you a huge bonus of pet experience. You have infinite normal infusions, but to be efficient, you should try not to go past the bonus pet fusions.

A good map for collecting a lot of pets at once is in the Crooked Canyon map. A good map to farm potion solvents is Cave of Eternity or Red Wall. Starpyy on Reddit has also shared a good spot, which is the Abandoned Charnel House in Logger's Hill, near the top-side portal. There are 4 spawning areas for the Stirges there, and you can go in a rotation where they will respawn as you get to the next spawn location.
