PokéBonk — What does Fourth option unlock, and how much does it cost?

Bonkfield editorial teamUpdated

The short answer

In Lab → Upgrades, Fourth option costs 3,000 Stardust and makes level-ups offer four choices. To unlock a fourth move slot, choose the separate 4th move upgrade for 1,500 Stardust.

What to check

Both upgrades are in the Run team section. Fourth option offers 4 choices at level-up; 4th move unlocks the fourth move slot. Lab Stardust is a progression currency, separate from the effect-area item in the Items directory. Check the current price in your Lab before buying.
