There are no cheats that are used to make the Wise Old King, also known as King Hagan, accept the player. This is because once the player submits a phrase, they receive a random score of either an A+, B or F. The score determines the number of Neopoints and the item that the player receives. The player is not able to visit King Hagan when he is out to study. This happens between 8 a.m. to 9 a.m., 1 p.m. to 2 p.m. and 7 p.m. to 8 p.m.
For an A+, the player receives a few hundred Neopoints and a random item that is usually of high value. For a B, the player receives around 20 to 50 Neopoints and a cheap book. The book is either about King Hagan or Brightvale. If the player receives an F, they get nothing, and King Hagan yells at them.
Because the phrase that the player puts in is graded randomly, the quality of the phrase has no baring on its grade. For example, the player is able to put in a phrase that makes absolutely no sense and still get an A+. On that same note, if the player enters in a phrase that is very wise, they may still be hit with an F grade. It is generally recommend not to put too much time or thought into the phrase.
