hi, I was wondering if there is some way you could have a skill that is one-time use but adds party members. The scenario I would like to use this in is: you are on a rescue mission to save a friend from a cell, but are caught in the act. I would (and can - I am using the yanfly engine) make it so that the player "learns" the skill just before the fight happens (really just un-hiding it) and it hides again after. The skill itself will be for breaking the cell door, and so the friend joins your fight. I guess it would use a common event, but how to do it, i have no idea.
