Isi's Silver Hourglass is a single use item that can be used on a Day Care to cause a single day care box to skip 25% of the overall timer for breeding after inserting all the required items. It can be obtained as a tier 2 special drop or from ultimate boss pokemon.
Trivia
- The hourglass's namesake, Isi, is one of Pixelmon's administrators.
- In older pixelmon versions that used the Ranch Block, Isi's silver hourglass was a single-use item that advanced a breeding Pokémon's breeding stage by one stage. It didn't work if the Pokémon was not satisfied with its environment.
