hi goodnight folks can any of you tell me howv to use the astrologist? how does he help to find the item? where do you go to see the item. thank you

You go to Manor -> Buildings, then click on the name of the Astrologist building. Underneath the picture on the new page it says what the building does and then there is a empty field that you can put the item's name in. Don't worry if you don't know the exact name, if you type part of it, the game will suggest items that have your letters in their names and you can choose one by clicking on it.

i did that but i dont know where to go after that. i went exploring islands but i dont see any. so i was just wondering where do i have to go to see the item. thank you

Exploring is the right place, it's just that if what you are looking for is very rare to begin with, it will still take a while because it's an increased chance of finding it, not a guarantee of immediately getting the item.

Also, your chances are lower/it will take longer if you only have a low level Astrologist.

thank you
