# Equipment Requirements [XP]

# www.ultimateam.pl

#===================================================================

# 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 simply configure requirements below (separately for each

# weapon and armor), according to the formula:

#

# WEAPON [weapon ID] = [lv, maxhp, maxsp, str, dex, agi, int, [skill_id, skill_id, ...]]

#

# For example:

# If you want a character to equip a weapon ID 2 at level 6, provided that

# it has 120 max HP, 40 strength, 70 intelligence,

# type in configuration below:

# WEAPON [2] = [6, 120, 0, 40, 0, 0, 70, []]



# Next, to equip an armor ID 3, which "requires" adequate agility

# and knowledge of the skill ID 10 and 40, type:

# ARMOR [3] = [0, 0, 0, 0, 70, 0, 0, [10, 40]]
