Set temporary char variable on attack

[Truly]

Hey guys, I have a very very tiny request here. I basically just want a variable "@onhit_mobid" to be set when you attack a monster. All it will do is set the variable = the mobs id.

Any help is appreciated,

thanks~

"Attack a monster" is a very wide term. Do you mean physical attacks only or any kind of attacks? What about reflected attacks? What about attacks that hit multiple monsters, like any AoE spells (eg Storm Gust) - you want only one monster ID, so which monster should be chosen in such situations? What about attacks with help of mercenary or homunculus?

Well to be more specific (sorry for that), it would need to be strictly melee, close ranged.
