The Temple of Trials is an area that holds a series of tests that Oliver must overcome in Ni no Kuni: Wrath of the White Witch. It is the home of Supreme Sage Soloman, mentor of the Great Sages. With Rashaad's convincing, he allows Oliver to go through the trials that will make him a sage-in-making.
The tests included the Trial of Wits, the Trial of Friendship, and the Test of Strength. The Test of Strength involves defeating Bashura. The Trial of Wits is a series of puzzles that demand the use of the spell Puppet String. The Trial of Friendship is a dual-stick challenge that involves navigating two character through a maze simultaneously.
It is also home to what people call the Solomon Series, a competition pitting familiar handlers from all over the world.
