Looking for some help with a trigger-based ability

Heyo any reading,

Here's my problem. My girlfriend and I are attempting to make an AoS map of our own, mostly for fun and to develop mapping skills (mine, specifically, since I'm the one doing the grunge work ^^;).

At the moment, I'm just attempting to get a few of the more 'interesting' ablities to work properly, but the first one up I've already hit a snag.

The ablity in question belongs to a Diabloist hero and it's called Caveat Emptor (Let the Buyer Beware). Effectivly, what I _want_ it to do is temporarily give an allied non-hero unit a big boost, while very rapidly draining their life. Then, when they die, they explode and cause AoE damage to near by enemy units.

The first half of the ability is easy enough. I just based it off of Unholy Frenzy. It's the second half, the explosion, that I can't get to work. The unit dies and thats it. There is no explosion animation, no AoE damage, nothing.

I've read through the forums some and found out a few things already, like that the game can't detect buffs on a dying unit, but even taking that into account in the trigger and using 'Condition: (Life of ((Triggering unit)) is (Less than or Equal to) 0)' instead of 'Event: Unit Dies' Results in nothing.

Is there anyone around here who might be willing to give me a hand with this? And maybe be willing to answer a few questions if I get stuck again?

I wanna _learn_ how to do this stuff, not just have someone do them for me, but so far I'm failing to even get what seems like a simple trigger-based ability to function, so I'm not at all afraid to admit that I could use a guiding voice. ^^;

Use the Doom ability. Just give the unit summoned by that the goblin mine AoE Effect on Death ability and use a trigger to kill the summoned unit when it is summoned.

Another option- try to detect the unit with the buff, store that in a variable, like Buffed_Unit1.
The make another trigger, Event- A unit dies. Create an If/then/else, compare the dying unit with the variable Buffed_Unit1 in the If section, and put in the other trigger actions in the Then/else.

Hope it helps, I'm not so good at triggering myself.
