O.k I was tired of seeing lame rpg's so I decided to investigate on ~Persona Rpg V.2~ and see how thay did the exp after a hour of looking I found the trick! Now I'm sharing what I learned since there was NO guide's on it! (I only take responsibilty for making the guide NOT THE TRICK! the person who I learned the trick off of is Arch_Nidhogg/FC_Nidhogg (I think thats his name lol))
Ok requires Age of Mythology:The Titan's!
Also you MUST have a basic knowlage of trigger's!
