Help the Monk
This Mystery can be found on a road southwest of Earnningstone. When you speak to the monk, he tell you that his cart has overturned and he’s dropped his juicy apples. You can then carry the crate of apples for him, and he will lead you to the farmhouse where you’ll meet his friends.
When you arrive at the building, drop the crate near the table outside to complete the Mystery. Surprisingly, this isn’t a trap! It’s just a wholesome group of monks eating some apples. You will receive 1,200 EXP and you should also loot the buildings as there are a fair few silver pieces to collect.
