Maybe, there's a possibility to reduce the cost of passives through the Item Mall?
As the games grown, more and more have been added, including the level 225 + 250 passives, and it's just gotten to be absurd imho
It costs 2900 IM Points for full passives for your class (Attack Power\Attack speed for weapon type)
It costs 10150 IM to fully passive a character through the General Item Mall passives
and if you want the weight passives that's an extra 750.
That totals 13800 IM for full passives, $138 to passive ONE character.
Trying to purchase this in game by purchasing passive books from players in game, given the market at the time would cost roughly around 400B Zulie
