Remember that tomorrow, 27 May 2020, is Dragon Quest Day. This represents the 34th anniversary of the series, whose first entry, the original Dragon Quest, was first released on 27 May 1986 in Japan for the Famicom.

As part of the celebration, if you are playing Dragon Quest of the Stars, you will receive neat bonuses. For those who hadn't, now is the perfect opportunity to do it as all previous events will be available once again fro a short time in celebration of Dragon Quest Day. Don't miss the chance to get the rare items from the original DQ games.

I am currently playing to the post game and i was wondering if i can regain the hexagrams gained during the search for my companions ?

Edit: I found it.
