To search for devil fruits, characters must declare a Devil Fruit hunt is taking place. Players must spend a week actively searching for Devil Fruits. At the end of this search, everyone must make a group check, using either Wisdom (Survival) or Intellgience (Investigation or Nature) to beat a DC determined by the island size. If more than half of the party succeeds, one Devil Fruit is located by the creature with the highest roll. Additional searches may be may be made if there are more Devil Fruits to be found on the island.
To engage in a Devil Fruit Hunt on an island you must spend 7 DT which will also lower the amount of DT activities you can partake in a week by 1. You only get a single roll and must return to the island should you leave it for any reason.
