A one shot, poison (stackable), melee attack?

[All_Out_Mapp]

Quite simply, is there any skill already existing that I can create a custom skill off of that will do just that: a one shot (cast with cooldown), stackable poison attack as a melee-type strike?

Or is this just barely complex enough that I'm going to have to create a triggered spell?

on-attack effects (aka orb effects) as well as spell effects (except for custom auras) never stack imho. you will have to trigger it, which is also not that easy as you would need the a unit takes damage event everybody learned to hate.

By "melee-type strike," do you mean melee range (100-150ish)?

Could you clarify what you mean by "stackable"? Is it something like: if you cast it to an enemy once it deals 5 damage every second; cast it again on the same enemy and it deals 10 damage every second; and so on?

With more clarification, we will be able to answer better
