What is the ultra wormhole shiny rate for Pokémon ultra sun and ultra moon

Solution 1:

According to the information on Serebii, the chances of finding a shiny increases by both light years and the type of ultra wormhole you use.

Another thing that changes as you progress through further Light Years is the chance of encountering a Shiny Pokémon. The further you go, the higher the chance is that the Pokémon you will get is a Shiny Pokémon and the wormhole also factors in capping at 5,000 Light Years at 36% in the Type 4 Wormholes.

The formulas below are the chances of finding a shiny by wormhole type

Type 1

1%; Top Rarity: 1%

Type 2

1+(min(9,((LightYear/500)-1))%; Top Rarity: 10%

Type 3

1+2(min(9,((LightYear/500)-1))%; Top Rarity: 19%

Type 4

4(min(9,((LightYear/500)-1))%; Top Rarity: 36%

So using 1000 light years, the percentage chance of finding a shiny can be calculated to:

1. Type 1: 1%
2. Type 2: 2%
3. Type 3: 3%
4. Type 4: 4%
