[SOLVED] Adding skill effects on Existing Skills

[pajodex]

So,

I was planning on adding some NPC_Skills in my server, however some skills doesn't have skill effects such as the ff:

		case NPC_ACIDBREATH:
		case NPC_DARKNESSBREATH:
		case NPC_FIREBREATH:
		case NPC_ICEBREATH:
		case NPC_THUNDERBREATH:

Where can I add this code:

clif_specialeffect(bl, <EF_ID>, AREA);

for each of those skills listed? Thanks in advance~

Edit SOLVED:

Thanks to
 @Stolao (discord) for suggesting to put it on where it defines the damage.
