Is this scenario possible at all? It'd be pretty impressive for my RPG if it was:
One character uses a skill with the name (let's say): X. However, he has already learned another skill named Y which will not show up in his list of skills in battle because it is conditional. The character uses the skill and because he has learned the skill "Y", it is used right after "X" is dealt, but also the character knows the skill "Z" which is also conditional and does not show up in the list of skills, and so skill "Z" is automatically used right after "Y" making it so that in total, the the skills "X", "Y", and "Z", are dealt in order as a result of the character just using the skill "X".
