[VX] SoS Skill and Item Criticals (v1.1)

[Serpentofshadow]

SoS Skill and Item Criticals
Version: 1.1

Introduction

Allows for skills and items to critically hit. Can be based on an actor's normal attack critical or on a factor of their SPI. Many options to make the skill work how you want. Can even set for certain skills or items to have a higher crit chance.

Changes are listed at the beginning of the script.

Features

• Base it on an actor's natural crit chance
• Alternately can base it on SPI if the spell is magical
• Works for both actors and enemies
• Can be set to work with items
• Can be set to work with healing skills
• Many options allowing for a lot of customization

# SETUP

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

module Serpent_Critical

  #Skill critical chance is the same as normal attack critical chance

  # Setting to false will base it off a stat

  # When false, the skill's atk_f and spi_f will determine the crit chance

  # If a skill has both then it will take the average of the two chances

  #Default is false

  SAME_CRIT = false

  

  #Determines how many points in the chosen stat will result in 1 crit chance

  #Default is 10

  STAT_MOD = 10

  #This affects healing skills

  #Default for this script is true

  #Default for RMVX is false

  NEGATIVE_CRIT = true

  

  #Determines if Items can critically hit

  #Default is true

  ITEM_CRIT = true

  

  #Determines if Healing Items can critically hit

  #Has no effect if ITEM_CRIT is FALSE

  #Default is true

  HEALITEM_CRIT = true

  

  #Chance a healing item will crit

  #Has no effect if ITEM_CRIT or HEALITEM_CRIT are FALSE

  #Default for this script is 2

  #To make it the same as the default crit chance, set to 4

  ITEM_CHANCE = 2

  

  #Multiplier for healing item criticals

  #Has no effect if ITEM_CRIT or HEALITEM_CRIT are FALSE

  #Default for this script is 2

  #To make it the same as the default crit multiplier, set to 3

  #NOTE: Only items that deal damage or recover HP/MP will be affected

  # This also depends on the above settings

Instructions

Place in the Materials section just like any other script.

By default it is set so that the skill determines the critical chance. If a skill has an ATK-F of 1 or more then the normal critical chance is used. If the skill has a SPI-F of 1 or more then the actor's SPI comes into play. By default it is set so that every 10 points of SPI would give a "magic" skill a +1 Crit chance. If the skill uses both ATK-F and SPI-F then an average of both is used.

When using this method you can change the SPI modifier under the module "Serpent_Critical" (in the script). Change the number to whatever you want. The default is 10, which makes it 10 SPI for 1 Skill Crit chance. Note that this does NOT affect the actor's actual crit chance with normal attacks.

In order to change it so that only the actor's default crit chance is used, under the module "Serpent_Critical" (in the script), change "SAME_CRIT" to true.

FAQ

No questions have been asked yet.

Compatibility

MAY conflict with any script that modifies "def make_obj_damage_value(user, obj)" in Game_Battler.

If using any alternate battle system, such as the Sideview Battle System script, just place this script BELOW it.

Author's Notes

I am taking suggestions for future versions of this script. I'm considering looking into adding an option so that this can be turned off for monsters. Also may add options to allow for stats other than SPI determining crit chance for skills.

Might add in support for weapons and/or armor giving a bonus crit chance to skills and/or items.

Terms and Conditions

Free for non-commercial use so long as I get credit. For commercial use, please e-mail me.

If you are using this script, please let me know. I would merely like to see the games that use it. :smile:

Well i have one how about having certain weapons have crits based on different stats.

Like long range weapons based on Dexterity And skills that involve weapons based on the attack stat.

I have updated the script to version 1.1 with many new features and a key bugfix. See the first post for more details!
