Run script (NPC) / or sound when using a skill

[Arkwright]

Well, I'm trying to put some voiceovers when using a skill, but do not quite understand the source, then come to you asking for help.

Let me give an example:

When a player uses the skill StormGust, while a sound to play the data folder on the client.

I thought of four ways:

1st - When the player the ability to use a script (NPC) was executed with the command to run the SOM. In the source there is a command that calls a script. Something like this:

struct npc_data* nd;

	nullpo_retr(-1, sd);

	switch(atoi(message)){
			case 1: nd = npc_name2id("CodeBuff"); break;
			case 2: nd = npc_name2id("CodeAnun"); break;
			case 3: nd = npc_name2id("CodeQuest"); break;
			case 4: nd = npc_name2id("CodeSom"); break;
	}

	if (nd == NULL){
			clif_displaymessage(fd,"...");
			return -1;
	}
	run_script(nd->u.scr.script, 0, sd->bl.id, nd->bl.id);
	return 0;
}

(I took this from a custom command, which when used, runs one of the scripts)

I do not know if you can use it in the structure of ability.

2nd - If, in any command that runs directly from a source media file.

3rd - A command similar to "OnPCKillEvent" but instead of running the code to kill, execute a code where when someone used a skill, perform the function. Something like: "OnSkillUsed."

4th - Create a new effect with the sound, but how?

Well I'm sorry my English. I used Google translate.

I'll be super grateful if someone help me. hugs.
