This script provides functionality

This script provides functionality for setting up "battle reactions", which are actions that are automatically invoked in response to certain actions. A reaction is similar to a counter-attack, except instead of responding to any attack, it only responds to specific "reaction triggers" and responds with an appropriate "reaction response".

For example, your actor might have a shield that casts "heal" on the wearer whenever the wearer is targeted by the "attack" skill. The reaction trigger is the "attack" skill, while the reaction response is to cast heal.

You can have multiple reactions occur simultaneously and all of them will be executed.
