# Equipment Requirements [VX]

#===================================================================
# Opis:
# The script allows you to set requirements for weapon and armor.
# For instance, outfitting a hero with two-handed axe would be possible
# only after reaching a specific level or having adequate statistics.
# Also added an option that allows to require certain skills.
#
# Instruction:
# To use the script insert tag into the "Notes" box located in the
# Weapon or Armor tab of the database:
#  <stat_require LV, MAXHP, MAXMP, ATK, DEF, SPI, AGI>,
# where:
# LV - required actor's level
# MAXHP - maximum HP
# MAXMP - maximum MP
# ATK - Attack
# DEF - Defence
# SPI - Spirit
# AGI - Agility
#
# For example:
# If you want a character to equip a weapon at level 6, provided that
# it has 120 max HP, 40 Attack, 70 Defence,
# add in the specified weapon's "Note" box:
#  <stat_require 6, 120, 0, 40, 70, 0, 0>
#
# Next, to equip an armor, which "requires" adequate agility:
# <stat_require 0, 0, 0, 0, 0, 0, 50>
#
# To set that the specified armor can be equipped only after gaining
# certain skill(s), add in "Note" box:
# <skill_require ID, ID, ...>
# where:
# ID - required skill(s) ID(s)
 
# For example:
# To equip an weapon, that "requires" skills ID 10 and 40:
# <skill_require 10, 40>
