Random Stat Variance for Items
Version: 1.0
Author: modern algebra
Date: August 7, 2011

Version History

• <Version 1.0> 2011.08.07 - Original Release

Description

This script allows weapons or armors to have randomly varying stats. So, one long sword could have 5 ATK while another could have 7 ATK.

Features

• Randomizes the stats of items you specify to the degree you specify
• Makes item drops a little more dynamic and can emulate higher quality and lower quality items of the same type

Instructions

This script REQUIRES Instance Items Base and must be below it, but still above Main.

It is very easy to use, however, and it will work for any item stat that is stored as an integer. All you need to do is use this code in the item's notebox:
      \VAR_stat[variance]
          stat : the stat you want to vary. It has to be a stat that stores an integer, and it must be the name of the method that returns it.
          variance : maximum amount you want the stat to vary by. It must be an integer. It will take a random number between 0 and this number and add it to the default stat value.

Valid stat strings:
ITEM - base_damage, variance, atk_f, spi_f, parameter_type, parameter_points, hp_recovery_rate, hp_recovery, scope, speed, occasion, mp_recovery_rate, mp_recovery, price, common_event_id
WEAPON - atk, def, agi, spi, hit, price
ARMOR - atk, def, spi, agi, eva, kind, price

Demo

Coming soon.

It would be cool if you could randomise the extra options for items, like Fast Attack for Weapons or Half MP Cost for Armours. But it's a great script as it is.

Also, any tips on using the send method for Objects? I looked into it before but it didn't seem that useful; here, you seem to have used it to it's fullest extent.

idk if it'll let you on the link but, this system allows you to change special attributes of items
