KSwap XP

by Kyonides

Introduction

Did you ever want to swap actors' skills or enemies' actions?
Or perhaps you failed to swap actor's weapons or enemies' atk attribute on you own.
If so, you would also need to be able to nullify such skills, don't you think?

Then you will be glad to find out that this scriptlet will make it possible!  

The Script

Code:

# * KSwap XP

# Swap the Skills of your Enemies!
# Heroes can swap the foes' ATK parameters.
# Monsters can also swap the heroes' Weapons at will!
# There is also a Nullify Swaps skill as well!
# Check the KSwap module and edit the CONSTANTS accordingly.
# You can prevent the party from casting the "Skill Swap" skill by turning on
# a specific game switch.

# * Aliased Methods * #
# Game_Battler#skill_effect(user, skill)
# Game_Actor#skill_can_use?(skill_id)
# Game_Enemy#atk and actions
# Scene_Battle#start_phase5

Side Notes

As far as I know it is compatible with the Default XP Battle System and those that barely modify it.
