Dekita's                                                                   v1.1
                             ★ Perfect EXP Curve™ ★

#===============================================================================
# ☆ Script Information:
#=======================
# As you may well know the default exp curve system in RPG Maker VX Ace is not the
# most dynamic exp system...
# Below is a chart to show the minimum and maximum values that you can acheive
# by using the default system
                      #---------------# #---------------#
                      # Basis 10 - 50 # # extra  0 - 40 #
                      #---------------# #---------------#
                      # Acc A 10 - 50 # # Acc B 10 - 50 #
                      #---------------# #---------------#

            #-----------------------#     #-----------------------#
            # Exp using min values  #     # Exp using max values  #
            #-----------------------#     #-----------------------#
            # Level 10 = 1400       #     # Level 10 = 10,569     #
            # Level 25 = 17,782     #     # Level 25 = 172,449    #
            # Level 50 = 89,936     #     # Level 50 = 1,319,088  #
            # Level 99 = 287,815    #     # Level 99 = 7,738,286  #
            #-----------------------#     #-----------------------#

# Via the default system is is very difficult to acheive lets say a very low
# amount of exp needed at low levels and a very high amount needed at higher
# levels or have a set amount of exp per level
# e.g lv1 - lv2 = 100 exp , lv2 - lv3 = 100 exp, lv3 - lv4 = 100 exp...
# with this script you can acheive a vast number of unique exp curves.
#
# NOTE: if you dont insert a notetag into [x] class then [x] class will use
# the default exp curve defined in the database under the class tab.
