Intro | Encyclopedia Harry Potter OP Guide

Unlocking all the secrets takes some time. There are tons of details which sometimes can be found very easily, but other times cannot. The Discovery Points are hidden literally everywhere, so do not hesitate to use all the items that seem to have some potential (they pulse when you check how many percent of the points you've found in certain area). Remember that you'll also be able to walk around the Hogwarts and collect points and other stuff in the Endless Day mode, after finishing the main storyline. In this encyclopedia you will find hundreds of tips that will help you to find most of items, NPCs or anything required to achieve full success.
