A Timer Ball is a somewhat different Poké Ball that becomes progressively better the more turns there are in a battle. Every turn, starting at 1×, a Timer Ball will increase in effectiveness by 0.3× (additive), with a maximum catch rate of 4× (11th turn and onwards). It can be obtained by crafting it, buying from a shopkeeper, or as a tier 1 special drop,
Crafting
Timer Balls are crafted similarly to other Poké Balls.
