Well I can't find that battle system you're using, but guessing that (like most of the battle systems) it doesn't change anything in Game_Battler class you can use this script.
EDIT: Sorry didin't see you wanted this for RMVX. I made a RMXP version. I made RMVX version also.
This is RMXP version

Make a state in the database and call it Wound or whatever you will, then in script modifiy STATE_ID to the ID number of that state in the database (for example if you see 008: Wound in states in database then write STATE_ID = 8).
