Specific Mime Skill

I have a specific request for my project's progress. Since I am not able, nor have I have the ability to do so, I would want to request this. I have searched the master list and somehow the mime skills I've seen are not quite specific and not applicable to what I want. I want a mime skill that specifically works this way:

when an enemy uses a skill to the actor (bearing the a note tag <mime> for example), a mime skill available for the actor when used would apply the same skill the enemy used to him or her. So basically, instead of copying an enemy's skill the enemy used on to any member of the party, I want a skill where it only works when it is used to him. When there's no skill applied to him, the mime skill of the actor would just be a normal Attack.

Thanks in advance.

If I understand correctly you want exemple when the actor or the enemy use a specific skill on a enemy this will do in simple a sort of counter attack? 

exemple

Monster A use Ice slash

Nio don't apreciate that and counter with Fire Slash?

What I mean is, for example, if an enemy, say for example a Slime casts Water I to that specific actor, then the Mime Skill when applied should be Water I for the rest of the battle. If the slime uses Fire I to him again, then Mime becomes Fire I. The thing is this skill is specifically for just that actor tagged with <mime>.

Hooo A sort of Mirror style character the character skill change with the attack he received right?

Yes, exactly :D

I think you can do this via the Actor class 

and after go in the Skill class....if you give me few day I can check what i can do ;3!

just ask for optio 

this change all skill 

or just one skill? 

like exemple I am a water type so I use water skills

but I get hited by wind and become wind 

so my skill become wind skill type?
