The Ikari system, known to Lufia fans as IP, was probably the most creative thing implemented into Lufia II. With the Ikari system, there were 3 gradient bars during battle. They were HP, MP, and IP. IP increased as damage was sustained through enemy attacks, and if a character had enough, then that character could use attacks assigned to specific weapons. If a character lost all of his/her HP during battle, the IP would reset to 0. IP was measured in a percentage, and different attacks required different amounts. As a side note, if anyone can make this script, I would appreciate a record of the code used to implement the weapon skills.
